@ Arria.
You know people in such stores knows a whole lot of what is really going on. Way more than you´d think.
I know when people are buying stuff that they are gonna use to make home made booze for example when they tell me that they are using it for something completely different.
Same goes for hardware stores.
My guess is that My girl were blushing when I sent her to buy some rope too so your blushing there isnt unusual lol
gotto love blushing girls!
