I've got this customer (Chinese) whom I've met just twice now, and whenever she's in and I've finished the job (4-bed town house) to collect my dough, she says, "okay, I'll just go around and check all the windows, and I'll be back" LOL That's the 2nd time now, and both times she's just comes back a few mins later and happy to pay me. I find it so damn odd, and can only put it down to being Chinese culture or something, I dunno!?? You'd think she'd sneak-check after I've cleaned the tops or something. Anyone else experience this??
