>>21411416 (OP)It makes the owner of that restaurant more money. You don't have customers taking 300 napkins, 57 ketchup packets, drinking 13 gallons of soda, spewing diarrhea all over the bathroom and leaving a mess for the employee to clean up.
You sell the drive thru customer exactly what they wanted, 10 napkins, 3 ketchup packets, a cup of ice and a shot of soda and they fuck off until tomorrow.
Its just faster and more profitable. Did you notice after covid ended a lot of restaurants kept doing drive thru only because "not enough employees"? They can run an entire restaurant with 3 workers instead of 6 to monitor the register, clean the dining room, clean the toilets, and giving karen a free apple pie. They can also turn the AC to a higher temp and turn off lights too.
I hope this helps.
