IF you got a bad meal at In n Out, it had to be a very unusual thing.
I have eaten at their locations since about 1965, and still can get one in Carson City, NV.
They are fresh, and they still sell the same basic menu. Fries are cut & deep fired within 6 feet of the stations. NO frozen fries.
IF you got a bad meal there, I will apologize for them. I know they are all family owned-—NOT a franchise. In over 50 years, I have never had a bad In n Out experience.
We lived in CA for 10 years so I’ve eaten there at least 100 times. Not “bad meals”; I just think their food is terribly over rated.
