One thing or the other, not both.

There’s a storefront not that far from where I currently live bearing a sign that says “Donuts and Chinese Food”. When passing it by one day, I asked a work colleague about it. He claimed to have tried every Asian-themed restaurant in the area. He said “Yeah, they need to pick one thing or the other and not do both.”
I had a similar reaction to this bit of signage on a recent trip to my home town:
I’ve had good donuts. I’ve had good burritos. I’m not sure it’s possible to do them well at the same time.
