I drive for a yeshiva and get paid for it.
One time the guy whos my boss in the yeshiva asked me if I can drive him to beni brak as a favor and I agreed.
It ended up being me picking him up from his house, going to some place that had a cheep sale, waiting around for an hour on a street with no parking, helping load the entire car with yom tov products for 3 familys, driving around beni brak in erev chag traffic, and shleping very hevy packages of stuff up multiple flights of stairs in 2 diffrent buildings with no elevator.
At the end of the "favor" that took 5! hours he comes over to me, puts 50 sheck in my shirt pocket with a huge grin and says: Enjoy!
