Red Robin review: Manager told me I was inconveniencing them

I took my children to Red Robins today (4/5/2021) at 5:30pm to location (40 N Dupont Hwy, Dover DE 19901). My family eat at this location very often. Today I order to sets of original wings and requested for all flats because I don't eat the other pieces. I was willing to pay extra if I had to. The manager told me know and that I was inconveniencing them. I was very polite and ask her again and told her I would take my business else where and she told me well were not doing that. I have been eating at this location for at least a year and a half and they always give me flats. I ended up leaving with my family and went to Buffalo Wild Wings.
