Quite right. How dare the old and infirm spoil the enjoyment of others. You are very selfish and if you are lucky, you may live long enough to become a 'bit less able'. Another example of Me Me Me attitude
Take a small towel with you and wet it as often as possible, then place it on the back of your neck. The evaporation will help to cool you down. Keep it wet with water from drinking fountains/restrooms or a bottle of water
I'll scout one out and hold it while my husband is ordering food. is exactly what is causing the problem in the first place. People sitting at tables with no food while another family member stands in line waiting to be served
Unless you have a member of your party that cannot stand while you are waiting to be served then you should not occupy a table. If somebody is in a wheelchair, then there should be no problem in them waiting for the rest of the party before finding a table.
Common Courtesy realy
