I accidentally ordered a chicken gyro (meant to order red meat version) but had indicated in the instructions that I have a chicken allergy. The deli sent the chicken meal. Fortunately I noticed and didn’t eat it. GrubHub customer service refused to refund because the order “was correct.” They said that if a restaurant ignores allergies noted in the instructions, the order is still correct. There is no other way to indicate allergies. If the chicken hadn’t been obvious, the consequences could have been serious. It also made me wonder if noting things in instructions like - use light mayo, no onions, etc, - can always be ignored and the order would still be correct?!?!
