Actually, most of the people I know in my area (NW Illinois) refer to a BADGE when talking about a badge of rank, such as Tiger, Wolf, 1st class, Star, etc. But when talking about activities (like Klondike Derby, Pinewood Derby, Camporee, etc.)we say PATCH. Also, Council and troop/pack designations are called PATCHES. I don't know if other US areas make this distinction.

Lets not forget items that use the same word but diferent spelling...
tire
color
honor

Most badges in the US are patches except except when it comes to Webelos acivity badges which are pins.
We refer to badges of rank here in the US , but I remember at the '80 Essex Jamboree in England trading my patches for badges.
Growing up in NE Illinois we drank pop, went to student council camp in southern IL, they all drank soda....moved to Atlanta 9 years ago... Everyone drinks coke. Doesn't matter what it is, could be orange coke, grape coke, if its carbonated it coke, even if its pepsi-coke.

I don't know what part of England you are from Pint?
Of course to my mind we have London and the rest of the country. London being where everyone wants to be!!
Thanks to the power of the telly (TV) most American and British young people are fairly well versed in both American English and the real thing.
Back home we of course have the Queens English, which sounds like someone trying to talk with a mouth full of pebbles.
We have all the regional dialects, which can change from county to county or even hamlet to hamlet and we used to have BBC English, many will remember the voice of the BBC during world war two: "This is the BBC.." (where I used to work!!)
Of course some things that become acceptable slang have double means. I remember Her Who Must Be Obeyed (Which comes from the Rumpole of the Baily books) riding on a bus and bursting out laughing when she seen an ad for "Fagots in Gravy" the fagot being a small meat ball. Is is also a small bundle of wood. She also had people do a double take when she said she was taking her Grand-pap home Suspenders. Everyone at the table thought her Grand-pap was a little odd, she was of course taking him braces.
If you ever get the chance there was a really good TV series on The History of English. I found it really odd that they claim that the best English is spoken by the people of Dublin Ireland.

999 = UK emergency phone number
911 = US emergency number

UK = Petrol
US = Gas

UK petrol (gas) price = high

doing a rough conversion the price of petrol in the UK is equivalent to at least US$6 per gallon

UK: a licence is required by law to watch/receive any broadcast TV channel which costs 126.50, this funds all of the BBCs broadcast TV channels and Radio stations in the UK

US: everything funded by advertisisng/sponsorship.

Not all TV/Radio is sponsored by advertsing/sponsorship anymore. Our Cable and/or satellite bills can pile up.
Of course you don't have a choice. You have to pay the licence (license) even if you have SkyTV

In the UK you need a license for your pet fish.

There used to be a Dog licence, but that went a good few years ago.

The cost of a UK Dog license had remained unchanged for nearly 100 years.
It was Seven Shillings and Sixpence.
Things remained unchanged until decimal currency came along.
Where there used to be 20 Shillings to the pound and 12 pennies to the shilling, that changed to having only 100 pence in a pound.
This of course meant that one new-penny = 2.4 old pennies. So the halfpenny which had gone the same way of the farthing (0.25 of an old penny) came back.
This made the cost of a dog license 37 1/2 pence.
But then they did away with the halfpenny.
In 1987 the dog license was abolished. Only about half of dog owners had one.
There is however a dog license in Northern Ireland and it costs five pounds a year. Which is cheaper than in the Republic of Ireland where it costs 12.70 euros a year!!
The House of Commons did a research paper on dogs in 1998:

Where I live we have to have our dogs licensed.
When we had Rory "Fixed" we were able to get him a lifetime license, we had the option of having him micro-chipped or tattooed. We went with the tattoo. Up until that time OJ had his heart set on getting a tattoo. I said if he got "Fixed" I'd allow the vet to give him a tat.
Strange I haven't heard much about him getting inked since. - I wonder why?
