I got a french drain put into my basement a few years ago by them. It was done over 2 weekdays. On the first day, about 5 guys showed up to do some demo work, so that a shallow channel could be created in the concrete floor along the walls of my basement. They arrived at 8:30, but didn’t start work until about 9:30. They took a short break after an hour. They took a one hour lunch break about 12 and resumed at 1:00. Then they started leaving at 1:45. I asked why they were leaving so early, and the leader said that jackhammering is hard work, and I shouldn’t expect their guy to do too much! Why couldn’t one of the other 4 guys do some of it? He said they’d be back tomorrow, since they were nearly finished.
The next day they arrive around 9:00 and finish in a couple of hours. Which means they could have finished the day before and not made me take an extra day off from work! Obviously, I wasn’t too happy, but I paid them without complaint. But the five guys were lined up outside and when I made the payment, a couple of them said out loud, «What, no tip?»
Wow, really???
