Ive started cleaning at the front and made my way around to the back and by the time I finish the buggers have got in their car and drove off. How rude?
The same happened to me once. It was Winter, windy and I was wanting to get to the next house so I could keep moving to keep warm; so when I knocked for payment and didn't receive an answer I knocked, and knocked again. Still no answer.
It was freezing and it took a couple of minutes for the penny to drop and I'd realised she'd just buggered off without paying me; and there's me hanging about on her doorstep, brass-monkey style. Now it was always difficult to get payment from this customer.
I was so cross I didn't know whether to 'poo' or turn blind.
I eventually was paid; I didn't say anything; I just didn't go back. Two-or-three months later she bumped into me and with a big smile asked me when I was going clean her windows!!!
I was polite and professional; but she left after our 'one-way conversation' not looking so happy; and I smiled!
Dissapearing customers; that's a big pet hate of mine (depending on the circumstances though).
