Generally its bar rules then?
Whoever was their first gets on/served first, but sometimes someone whos loud (or has a bus pass) will be out of order.
I have only seen one bar operate a queuing system quite a silly idea, as its never really busy, and when its really quiet they have normal bar service, and then a queue kind of appears, and the staff go crazy at you for not being in the queue, despite being there longer than the queue has
Bars and bus stops have one important thing in common - the busiest/biggest ones are where problems are more likely to arise, as in the smaller or quiete rones everyone knows who got their first!
I normally do the same. The only occasion I don't is when coming back from work, and it would mean waiting for an hour and a half in a village with no facilities for my connecting bus. I actually walk to a stop before the school and sit at the front near the driver - this generally avoids any problems. The children from this particular school all rush on at once and just dump return tickets in the drivers cash tray, this occasionally causes problems when a child hands over a screwed up single ticket, instead of a return. Causes a delay while the driver tries to get someone to own up, but on the whole the kids behave quite well (occasional fare evasion aside). I suppose it helps that the bus is only a 33 seater.
I've used another bus originating from the same school, when my normal bus had been cancelled due to an emergency road closure. This was much worse, a double decker full to standing with kids shouting and swearing. The driver attempted to gain some control, but was given a mouthful of abuse from a couple of kids. The poor guy then apologised to me for their behaviour!
Two incidents in particular made me avoid school time bus travel. The first was in North London when I took an afternoon bus from Southgate to Barnet. Midway through my journey we stopped at some sort of educational establishment and the bus was suddenly swamped by schoolchildren yelling, shrieking, swearing and throwing things at one another. Mercifully, the agony only lasted for 15 minutes as by then we must have moved out of the main catchment area and most of them had got off.
The second time was in South Wales, when I was the only person on the bus until the school. The pupils were a bit older, and were talking very graphically about their sexual adventures, rather unpleasant to an innocent bystander!
I witnessed the same in Greece, or more precisely Corfu. I think I was 10 or 11 at the time, and was swept up in a stampede of locals waiting to board the bus. It was quite an experience - my parents regretted choosing to use the local bus, and a hire car miraculously appeared the next day.
On the subject of London, it's everyone for themselves. I used a bus from Heathrow Central bus station the other week, and it was ridiculous - especially considering the heavily pregnant lady who was trying to get onboard. It took around 10 minutes for someone to offer her a seat too!
That's my problem in London, often I have to push in front of people in the queue to wave down a bus that they are not getting on.
I must admit I have never seen a traditional queue line in central London, and I don't remember seeing many anywhere else either. I remember a photographer in Reading organising several of us into a line when we were waiting for a bus one day. The picture appeared in the paper to illustrate a story about a new mobility bus service that was being introduced, but before the photographer's intervention everyone was just standing around randomly as usual
