send me your number, I'll SMS you when I go out so you know to stay home
Here's my own observation (just part of the picture), here's an illustrative scenario for a typical (reasonably popular) WG
she arrives around 11:30 am
her first client comes a bit after 12:15
he probably won't stay long, the lunch-time crowd are on a schedule
and she'll be taking clients through the 'second' lunch hour through 2pm
the last lunch client usually finishes by 2:30
then she gets a break, and phones out to have lunch delivered, a bowl of noodles, or maybe a rice box
she's expecting to rest up until 4:30 or 5:00
but doesn't always
if she gets an afternoon client, she takes her time, not expecting a queue to form ...
then her first after-work client arrives around 5:15 to 5:30
and she's busy for most of the evening
finishing any time between 9:00 (if she's laid back) or 02:00 (if she's saving for something special)
Anyone care to add to that picture??
