"You People Don't Give Change"

Not sure of exact date, but occurred prior to 2016 presidential election. Elder Caucasian female went to purchase lottery scratcher tickets in a machine. Placed in $20 bill but the machine did not give change (stated on the machine). She was upset and stated never come in here again. Asian clerk stated people ask for change. The Caucasian female stated "you people don't give change, Go Trump!" and left the store.
