@Inna22 What on earth was she washing 3-4 times a day? Was she taking in laundry as a business?
It's a tricky thing to figure out at what point to cut your losses. I've had upholstery clients who I could tell from square one, just that feeling, you know, were going to be a pain in the butt and they turned out to be exactly that.
Changing their minds 3 times about what they wanted done, which entails doing yet another estimate, giving me a deadline they absolutely need it by because they have guests arriving, then when I bust my ass to get it done on time, and call to say it's ready, they tell me that's great, but they're out of town because the guests cancelled, so they took a little vacation.
I should have just told them from square one, when I could sense they'd be difficult, that I was slammed busy and really didn't have time to take on another job.
