re: ATTN Waiters: You are the Face of the Restaurant to the Customer

Not true at all.

What about servers who have three table sections in restaurants with an average $250 per table bill.
If you have 2.5 tables an hour, and work four days a week and take three weeks off, you still have like $140,000. High end servers can make bank.

(this assuming you average 18% tips, which is the standard not 15%)
