Out of towners pulling bar down without warning

Look I get it, maybe in your state it is required by law to pull a bar down but for god’s sake give a freakin’ warning. It is very irritating getting bonked in the head when some east coaster immediately starts yanking on it and clobbering me before I even get settled back.

Is this too much to ask of you guys? Just a simple “hey, bar is coming down!”. Not sure if anyone else has experienced this but it just annoys me that there’s no manners about it…
