A lot of what the OP said is hard for the hill to manage, but I do get irked on a busy day when the lift attendants are just sitting there and not shoveling any new snow or cleaning up the lift entrances/exits. I experienced this last weekend when the grooves cut into the entrance to the lift made it impossible to balance on your board... I mean deep 4 to 6 inch valleys and troughs, 8 in each entrance to the quad (not the line, but getting on the actual lift). The lifty could have just raked it out... but that didn't happen the entire day. Just icy valleys and awkward slipping around by every snowboarder there.
Same deal with the exit... they could have easily shoveled some snow on the ramp and raked it but the lifty sat on his ass until 1 or 2 PM.
