Unusually Persistent Sleazeball

What is it about sitting behind a reception desk that makes certain delivery men interpret civil conversation and eye contact as sexual availability? I am nearly always pleasant to the men who collect and deliver things not because I am in need of attention but because having them like me makes my job easier.

Today the UPS man was insisting that he wants to take me to coffee or lunch. I don't want to go to either but I'm not entirely convinced he got the hint. I expect I'll see him again tomorrow and he can hassle me some more while he's dropping off computer equipment.

I wish Imelda was there to help me fend off the pervs. Sigh.
