Twice now I've seen commercials selling the idea that waiting is a worthless time waster (I can't find a good reference but I'm sure you've heard them), One in particular outright says "No one has ever gotten anything worthwhile by waiting" (paraphrase). Implying that waiting was bad (since they were selling the speed of their service).
It's odd that they can actually get away with disparaging waiting. Waiting is an excellent exercise in patience. A sort of zen-like opportunity to work on breathing and relaxation, reading, writing or thinking.
I find it also helps to realize that as long as you are taking up their space it's quite likely they will get to you. It's hard to ignore a human. Humans take up space and a business only has so much of it. Not dealing with you is actually costing them money, so they have an incentive to work with you.
Waiting is not so bad. Really.
