After reading the thread about tipping movers, laborers, etc., what about occupations where people have expected -if not outright asked for- a tip when there is no reason to tip them? Tip-hustling, I guess it is. We recently went to one of those self-serve frozen yogurt places. You know the kind, it's like a buffet. You get your dish/cone, fill it full of ice cream, then go put toppings on it, then you weigh it and pay based on the weight of the contents. We went to one and the cashier, as we were weighing, said "I hope you guys enjoy your fro-yo" and, as he placed his hand on the tip jar, "And tips are appreciated!" He didn't do anything but hit the button on the tablet that calculated how much we were to pay!! Hell, if there was a way to make sure people knew how to ring up their own bill, there was no need for him at all.
