New Hotel Annoyance

I’m sitting in my hotel room and the maid is knocking on the door. She wants to come in and turn down the bed, drop a few chocolates off, bother me after I’ve just spent 9 hours talking and talking and talking. Its as if they just hang out in the hallway waiting for guests to return to their room. Maybe this is a new way to try to get a tip out of the patrons. It is so annoying. I just want to be left alone. This is all in the name of service I guess. Do the people that run these places NEVER go on business travel? When you get back to your room, the last thing you want to do is interact with ANYBODY. And every night at this doubletree the maid service comes ‘knock knock knocking’ to spend 15 minutes fiddling about the room. I have phone calls to make, haven’t checked my email all day, and instead I have to deal with this situation. I tell her through the door, ‘thanks, I’m busy’. I said the same thing yesterday and I'll say the same thing every day.
