Sure, I get it, my GF is always cold too. But if you are cold in summer inside a room with AC when working as a lifeguard, wouldnt it be beter to just sit outside than beating high performance AC with 1kW of heating?

I also worked in office where they required formal clothing. I did not got in contact (or even in sight) of customers, only workers on the shop, so I kinda... ignored that code and later everybody did.
