"Juan later inquired if we had included the wine tip in the total, to which we replied yes. He then seemed quite upset about our $20 tip on a $350 bill, and his demeanor became rude. Although we intended to provide him with the remainder of the tip in cash, he didn't wait to hear our explanation before reacting poorly towards us. Ultimately, we decided to give him only half of what we initially planned to tip due to his unsatisfactory attitude."
