I know some girls who work as 'shot girls' around my area. They are paid $20
per hour, under the table, and they keep their tips. They also are 'charged'
if they drop a shot or somehow or other fail to sell one/some, so I expect
they purchase the whole tray. They've told me that on Friday and Saturday
nights, working from 11PM to 2AM, they make at least $150 to $200, plus the
hourly wage, so 'shot girls' (if they're paid what my friends get) might think
your wages are a little light, although they wouldn't have to lug around the
shots, but depending on the area of the country, $35 to $75 for a 2 hour gig
might be pretty good. I concur on the college students, those are probably
your best bet for contacts. Good luck!
