If you read all 8 pages you still wouldnt. Basically some deliver/service type jobs pay the workers a minimal $ per hour.. usually $2 or $3, which is normally ok because they will make up the difference in tips (unless you get the cheap ******* which there are plenty just here in this thread). The employer is required to pay any difference in the hourly rate if the tips do not equal minimum wage for that state. So as to your comments above.. this does not apply to all job types (Doctors, Bus Drivers, etc). Common jobs that tips are expected are (but not limited to): food delivery (pizza, chinese), barber, waitress/waiter, etc. I tip my mailman/garbage man at holidays as well. Goes a long way when I need to throw out something that normally would require me to bring to the local recycling station.
It's not cheap to not tip someone who is doing their job.
I'm a legal secretary, should I ask for tips from the solicitors every time I finish an audio tape? Should they ask for tips from the court every time they finish dealing with a case?
Tips are entirely optional and it doesn't make you cheap not to pay a tip.
If the wage is really low and they rely on tips, then they need to try and find another job because that's not very secure, is it.. the company should pay the wage, not rely on customers to do it. You have a very strange point of view IMO.
