If I were going to get other people’s orders, I’d probably just pool the money and give them the change based upon an approximation of what it cost. Like if you got something for 4 bucks and something for thre bucks, I’d figure yours cost about 7.50 with tax. Presumably the people giving up the money are not going to nickel and dime me and vice versa.
For me, as a single order, I sometimes go in and sometimes do the drive through. If I feel like taking my time, I go in. If I’m in a rush for example I have to get home, I’ll do drive through and eat when I get home. In cases like that, though, I hardly ever do fast food as I’m usually not so desperate for food that I need to eat fast food at home. It’s usually a “road” meal that I stop and get in my travels.
Id’ have no problem ordering for six at the drive through, like I said I’d pool the money and dole it out when I returned to the people.
