Quoted from vid1900:(OK, I've got to ask, have you EVER, even a single time in your life, overpaid anybody by $1700 ?? No?
How about by $100? No? It does not really happen, does it? )
I paid my plumber an extra $100 when he was doing some work for my new septic system....last time he popped over to check a clog in the basement drain hole it was N/C.
Always tip your contractors if they do great work!
