I had a customer approach me and asked if i had done her velux's, i said, "yes, of course, i always do them".
Turned out the reason she thought i hadn't was because they were dry. The velux's in question were in the sun, there was a moderate wind blowing that day, and they were the 1st windows on her house i had done an hour previously (when she approached me i had just finished the 3rd of three large house on that street). I dumped her shortly after that!
