Tax preparers. Urgent medical care facilities. Actually, I think drive-throughs should be for the handicapped only. I can't believe that people are so incredibly lazy that they can't get out of their cars and go inside the business. I have walked in and out of fast food joints faster than the drive-through lines. What a waste of gasoline.
Any and all. Yes, it's convenient to run by and get a coffee when you're traveling and don't need to go to the WC but they bring problems. Smartly run cities don't even allow them. My hometown did not even allow chain restaurants at all for a long time but eventually let a Wendy's open, but with no drive through. Now there is also a Subway but no drive through. The banks had drive through windows though. As far as drive-through things, the coolest two I've ever experienced were the Painted Desert and a Christmas program at a church in Eureka, California where you drive through to experience it. It was so cool and a beautiful Christmas pageant. My daughter and I drove through it and were blown away.
Mortuariesy. should be on that list. Driving by to see the open casket of Uncle Edward or Aunt Maude would be tacky IMO. Besides the bad coffee normally served would become a thing of ancient histor
