I am in AC on weekday mornings on occasion for work - and always with co-workers. Each time we go, we pick a number on how many high-end working girls we can spot in whichever casino we'll be working before leaving the work van. The entire group must agree she's a working girl to count. Fun times.
Case in point: If she's wearing makeup, high heels and a cocktail dress at 10AM on a Tuesday and in line at Starbucks, she's meeting her 1st client of the day shortly.
