Fame, I'm interested in your last post; I have waitressed myself when I was at university, I think lots of students do that. Anyway:
Thieving tables - this shouldn't be possible and it's on management to put in place measures to prevent that, ie. taking a card at time of booking or behind the bar? That would circumvent the thieves - and any dishonest staff who 'give' to family/friends.
need to exceed expectations - well they really don't, do they? They don't need to do that. They're getting a salary and they just need to perform their job. If they are so diverted from all of their other customers to 'tip chase' then that's perhaps a reason not to give that temptation?
NYE - come off it, waiting staff work for tips on this day/night and you know it. There was always a plethora of staff wanting to do this night - a bit like refuse collections...
14 hours without a break and being grabbed - you're obviously attributing this to bad and inefficient management, yes? Because receiving a customer 'tip' couldn't make this sort of thing worthwhile, could it? Or are you saying just that?
customer is paying for the food - yes they are - and they're already paying for the buildings, insurance, toilets, car parking, staffing and anything else the owner can load into the price. Or do you believe that the owner takes all of these costs on the chin?
Perhaps you've had some bad experiences of waiting and are projecting as bit? I'm taking your post at face value.
