Unwanted 3 a.m. UDON wakeup call

Lets just say I'm not a happy camper. Had the wrong room in the hotel. 

At 3 am they started a metal saw next door at the 7-11. They build a chicken sales stand and operated the saw for close to an hour. 

Had troubles getting back to sleep after the noise ended and now have a severe backache. And I didn't bring any pain medicine.  

I wonder if I can keep a smile on my face for the rest of the day. It's going to be a challenge.

Next time I stay in this hotel, it won't be a room facing 7-11 or the morning market, which gets busy at 5 am.
