compensation... for doing the job he is paid to do... right.
look, if you live at the end of a long shitty dirt road, or maybe the last apartment on the top floor of a 6 story walk up - then they're going above and beyond. Hell yeah, tip more.
Tip to be nice, because times are tough and you have some extra cash.
But don't tip because someone did the bare minimum that they get paid to do anyway.
Don't tip because it's expected. Don't tip if you can't afford it.
you, by simply spending what little you have and can, are helping pay their wage already. You're doing your part. That is: don't feel guilty if you can't or don't tip.
Do feel warm and fuzzy if you can and do tip, though. it's still nice to do :)
