Took some screens to be repaired at the local True Value type hardware store. I go there a lot, sometimes for small ftgs and such for work. I like it better than the big box stores, unless you need a shed or a pallet of wood or some crap like that.
Anyway, paid the lady, who I see all the time in there.
Thought I gave her 2- $20,s. she gives me change for a $20 and a $10. I questioned her about it but she said that is what I gave her. I couldn't be compleltely sure so I said OK.
They called and said my screens were ready and they added up the register and they had indeed goofed. So they had my $10 for me as well.
That would never happen at Homo Cheapo or WallyWorld.
