We've spent the last week or so doing the tourist thing in London (most expensive holiday ever and we slept at home!)
Most of the big attrations (London Eye, Aquarium etc) allow you to purchase a priority ticket for a few pounds per person extra, which means you don't have to queue. I know it can be done at Legoland and other theme parks too.
It just seems wrong to me though, that those with enough cash can not only jump the queue, but effectively make others' waiting time longer. It doesn't seem like the behaviour I want to demonstrate/teach to my DC, but at it seems to be the way of the world AIBU?
