Conspiracy

Sorry to be hogging the Green Room Gossip board at the moment, but this has been bugging me.

Question -
Why do companies decide to perform Summer-costumed/setting productions in the Winter, and Winter-costumed/setting productions in the summer?

How many plays at the moment are set in a warm setting, with actors in scant clothing I wonder?

And how many actors will consequently suffer the flu and share it around?

I'm sure there must be a few gripes out there at the moment..
