I remember I ordered a chicken sandwhich from this one restaurant in Frisco and some Asian cat came and delivered it to me. I paid him but he didn't have any change on him so I just gave him the exact amount. Then he gave me this sad face and looked like he just got his bicylce stolen by Deebo obviously becuause I didn't tip him. If you are a delivery guy or a taxi driver you should always carry change on you. If not you're playing yourself since Im paying it's not my responsiblilty to have the correct change to provide a tip. This was inspired by the thread where the cat is asking about Mexican restaurants that deliver.
