No way anyone outside of LA/SF/NYC were paying dishwashers 10+. I made 5.25 (i think) around that time period (98-00) washing dishes. It sucked ass
Hosts/busers started around $5.25 or so... I think I eventually worked it up to $7.50 or so, but with tips it was much more. My point is that even then it wasn't worth it to me to work for $10/hr.
If I had to guess, the wages probably aren't much more now than they were then.
