DaRuDe said Your mistake ...
You always pay after the job is done not before."

But they insist on payment before. So I insist on their receipt. The cheaters who look pitiful, lie and say "finish receipts", I say, "too bad. No need to wash. Thanks". Had one who magically "found" his receipt book when his hangdog look didn't work.

Haven't tried Souq but City Centre, a few times. No problems.
