Hi Steve,
Sorry you found fellow Brits so awful last time you went.
I do understand about the car queue incident, but that does happen all over the world! Have you ever been to Italy? Car driving over there is manic, no rules whatsoever!! And France, well you take your life in your hands there when you cross the road in Paris!! So it is worse elsewhere I'm sorry to say.
I went to Florida last August for the first time ever and to be honest I didn't see any badly behaved Brits at all, everyone is usually so happy and relaxed that it's all fun.
I only encountered 2 incidents that stick out in my mind. One was in Animal Kingdom and it starting pouring with rain, I'd been the day before and remembered that the Safari ride queueing area was all undercover, so I rushed there with my 11 yr old son to keep dry. The queue was already enormous and most of the time we all just slowly kept stopping and starting. Well one group of women - American - all very tall and very overweight, there was about 6 of them I think, started pushing forward. I was knocked flying and this girl didn't even apologise. Then more pushed past. The whole group were then in front of my son and I and I noticed that the whole lot of them stunk very badly of sweat. They were all black. But this hasn't made me hate blacks or Americans - they were just one family who had no manners. I moved myself and my son over to the other side, to get away from the smell and started chatting with the nicest family ever who were from New York and I really enjoyed the rest of the hour long queueing, before finally getting on the ride, with them! They were ever so interested in talking as the dad had been to the UK on business and he wanted to ask me lots. What I really loved most was the fact that I had an inkling on where they were from due to their accents! They, however, especially the mum, had no idea that they had accents!!! I thought that was lovely!
One thing I immediately noticed though, in Florida, was that American's do not do one thing, that practically everyone in the UK, myself included, are guilty of. They do not look you up and down and make a decision on you based on your weight, hairstyle, clothes worn, etc. That I found so wonderful. I am very overweight and over here I am made to feel so awful because people so often make their mind up about me just because of my size. But in Florida everyone just looked at my face and smiled and said Hello everywhere I went. Oh it was so nice and I felt so welcome because of that.
Still each to their own, we must all learn to be more tolerant of each other and personally I think it's worth a polite word to someone if their bad behaviour annoys you. Just make sure you don't show you are angry. Imagine someone coming up to you, if they are polite and just say, look please don't take this the wrong way, but what you just did, re queue jumping, shouting, whatever, I just wanted to say that I think it would be better for everyone if you didn't do that again, as it annoys people or whatever! You never know, it might work. If you are polite about it, maybe even add something funny, so you can all laugh together, may make them change.
