How horrible. My sympathies...
My wifi is shaky, due to a big crowd of people sitting at a table in between me and the door to the atrium... believe it or not. The A/P is on a straight line through the door and about 50 feet on the other side. I can't move without losing the signal. All I can do is wait for them to leave.
Maybe if I were able to annoy them somehow...
Become a MR. SHOUTINGMAN ;~d
