Jobs In Non Air-Conditioned Shops?

Maybe I should start considering jobs which are out of my comfort zone. I mean jobs in non air-conditioned shops.

There are actually quite a number of non air-conditioned shops selling scales, shoes, clothes and gifts that I can try to check out the vacant jobs, but I have been putting off walking in or calling for interviews.

You see, I shower 3 to 4 times a day. How am I going to stand 8 hours without a shower if I work in a non air-conditioned office/store?
