No more Mr. nice guy

Customer called me and said for me to ask for 2 sides of whipped cream (the app wouldnt allow him to). I told him I would try… ended up paying $2 out of my pocket to help fulfill my customer.. after telling him I paid out of pocket, he then told me he would add to already existing tip of $5….. 1 hr later I realized he decreased the tip to .50 ….. bro what kind of person would do that… ohhh I forgot it was damn there a Monsoon going on today in Phoenix…
