My kids have a severe allergy on certain food. I packed some food for my own kids and purchased drinks at the cafe. The director of museum asked me to purchase foods- horrible pizza, few selection of snacks- otherwise he said we have to eat outside (under the sunshine with 100 degree).
Even I purchased drinks, we cannot stay inside eating. The employee publicly embarrassed and offended me in front of other kids because I did not purchase SNACKS at the cafe.
