richer areas

do the richer areas tend to not give any tips when y’all shop there? i’ve been doordashing in the spots that are super busy and happens to be the “rich areas” around where i live and the orders have been 5, 3, and sometimes even 2 bucks where there’s not even a dollar tip added. i’ve drove to these huge mansions more times than i’ve counted where they don’t tip at all! i just don’t know if it’s just my area or it happens to others as well. it seems to be the people that barely have anything that tips the most. like trailer parks are the most nices and giving people i’ve delivered to, shouldn’t it be the other way around or am i just thinking to hard about it?

edit: also im always making sure to let the customers know when im about to drop off the orders and when im on the way to them; not to mention when they have a swing glass door i make sure to put it where the door won’t smash the food and also if theres like a table or chair ill place the food there so they don’t have to eat “floor food” (because i hate when they place the food on the ground with the bugs instead of placing on the little table by my door, so i could understand they probably would appreciate that i don’t place it there as well if theres a table or chair near the door)
