Glenn,

You'll find A/C in big commercial buildings, like supermarkets, office towers, etc., but not in the average small store.

As for residential, it's almost unheard of, as the temperatures here seldom get hot enough to warrant it. One or two of the mansion set might have it, but I've never worked on a house here with A/C.

By the way, it looks as though our heatwave is over. The temperature in my area is back down to normal.
