My DS has allergies but we always have his EpiPen and he sticks to food we know is safe.
For years we ate in a local cafe without issue.
It then got taken over but we saw no reason to be concerned.
We went in and ordered breakfast as usual. They asked if anyone had any allergies and we said, yes DS but that's OK as we've ordered the breakfast and those are all safe foods.
Waitress says she will be back in a bit so we assume she means with drinks/food.
Another lady came over to the table after about 5 minutes. Looked pretty pissed off
She didn't even introduce herself just days "I understand one of your party has allergies so we will not be serving you today."
No sorry, no explanation. I said to her that we had ordered food he was fine with but she cut me off and said "I'm sorry madam but we reserve the right to decline service and I must ask you to leave".
We were so embarrassed and DS, who was 10 at the time, was sobbing. We had never had someone react like that ever.
I reviewed them and said what happened but they responded that they stood by their decision. Eventually it went in the local paper as they did the same to another family.
The cafe lasted 6 months and was closed again. Frankly they deserved it.
