Hmmmm... Let's take these in order and try and sort them out:
1. Smoking... Despite my recent arguments, it's something that doesn't bother me, Furie! It does however bother others and makes Madame_Furie ill, so it does bother me by proxy!
However, it's likely we'll be using parent swap for many years to come, so it'll be me "suffering"...
2. Bad language... Neither Madame_Furie or myself swear in public places, or around children. We don't let Minor_F play games with swearing, or watch films with swearing... Therefore, we tend to get a bit ****ed off when people swear at theme parks!
The occasional swear isn't bad. Most kids only repeat words they hear often, or that are directed specifically at them. Background f's and blind's are mostly ignored... So it's annoying, unnecessary, but usually okay.
3. Q-Jumpers... Don't bother me at all. If I get the chance, I will tell the ride op, and get them kicked out of the line. Ride ops DO take q-jumping seriously, more so than smoking and swearing... I've had quite a few people taken off a ride because I told the op they'd queue jumped... You find the other people around you will also back you up...
4. Alcohol... Although I don't think it is needed at theme parks, as long as people don't abuse it and cause trouble, then I think it's fine. I'm oddly soft on this subject (which considering I have only ever had a bottle of beer once EVER in my themeparking career is strange). I think it wouldn't hurt parks not to sell it, it wouldn't be missed and it would be a sensible "pro-active" move. However, people intent on getting drunk wouldn't do it at the over inflated beer dispencaries at themeparks. They'll bring their own anyway...
5. Litter... Well... Go to Disney and look at the litter problem... Sheesh... Oh, there isn't one... That's because the park is well maintained so people respect it, and there's an army of litter pickers cleaning it up... People are the cause, but UK theme parks don't provide a solution...
So, my choice... It has to be between smoking and swearing... I can't really chose one over the other in terms of anti-social behaviour, but I'm going for smoking as it's actually against the rules...
