Tea towels= kitchen towels.
Toilet roll= toilet paper.
Kitchen roll= paper towels.
Ill= sick. I think in the U.S. when we've come down with something we say "I'm sick" as opposed to "I'm ill."
Torch= flashlight.
Car park= parking lot.
Store= shop. "I'm gonna pop round to the shop, Mum."
-At some supermarkets like Co-Op, you have to put a pound in to get a shopping cart (er, trolley

). But when you put it back, you get your pound back. A bit pointless if you ask me....
-You have to pay to park nearly EVERYWHERE.
-Don't expect to get very many compliments in Great Britain, Yankees. Here, it may be typical for a stranger to approach you on the street and tell you that you're wearing a fabulous outfit. Compliments in GB aren't widely accepted/given. In the four trips I've had there, I've maybe gotten 2-3 compliments.
-Most malls/shopping centers in the U.S. close around 10pm. Stores closing that late in GB isn't very common. I think most stores like in town centers close around 8 or so. Oh, I think most supermarkets close at 4pm on Sundays.
-In a movie theatre (er, cinema

), you have a choice of sweet or salty kettle-style popcorn. No buttered popcorn.
-My boyfriend does this: when he's given the check at a restaurant and pays for it, he'll just include the tip in with the amount. In the U.S. it's typical to pay your bill, then give the tip separately.
-I have to stop this now, on a roll! From personal experience *if you're going out late at night and park in a parking garage, it is very important to check the times of it to see if it closes.* Me and my boyfriend took a day trip to Lincoln once and ended the day with late night movie. When we got to the parking garage to go home, we were both shocked to see that it was closed!! I had never in my life heard of a parking garage closing! Apparently it closed at 11pm and the next time it would be open was like 6am next day. We were stranded and had to get a hotel for the night.
