Tipping is completely stupid and unnecessary. When a company pays an employee to do a job it is already expected of them to do the job well, the customer should not have to add in an extra "bribe" aka tip to entice the the worker to do a good job, they should already be paid for that, and if they can't perform their job adequately then the employer should not keep that person on.

I believe that the concept of tipping in America started as a way to get special treatment like skipping ahead in the wait for a table or a bartender being a little more generous in the amount of booze he puts in your drink. But somewhere along the line, tipping became common etiquette thanks to people like Emily Post.

On a side note, I don't get how a $1 tip is expected to have a bartender take the cap off of a bottle or else get snubbed the rest of the night if I drop anything less. Not that I don't tip, but this type of stuff is annoying.
