It is said, that if a frog is placed in cold water and slowly warmed, it will not exit the pot, but that if dropped into a hot liquid, it will quickly jump out. 13 years ago, I was payed $5 to take AN optional pic of an eatery. In that I was there, it was only logical to add to my fee. Slowly, though, over the years the pic was no longer optional and the number increased, but the fee remained the same; if one factors inflation, the fee actually decreased. It is the responsibility of a successful contractor to draw the line on what is or is not acceptable. After all, we are not employees.
