enlighten me, whats a crap customer?
Mainly the tight t*ats, the ones that always moaned about the price or the ones that didn't take well to a price increase.
Also the ones that never respected me i.e. house was always a mess, never moved anything, never had hot water on, they walked all over the carpet while i was cleaning, kids would mess around with my spotting kit, they where late, the once that canceled on me a few times, the ones that look over you etc etc life's too short to be putting up with that rubbish!
You know the jobs that make you say "F*uck!! i'm glad not ever job is like this!!"
p.s. usually a combination of the above, i'm not that fussy who i clean for as long as they pay lol
