That sucks, but at least you are not on vacation. If you are there for a class, then I assume they are paying for this trip?
Yeah the customer is covering my expenses since they chose to pay for an on-site class, so there is that.
Thankfully my congestion has let up a little bit, really hoping I can get some solid sleep tonight...but doubtful, just got back to my room and it is about 80 degrees inside.
