There are some venues that won't even allow an entertainer to use the regular hallways or elevators if they are using a wheeled device. I've been directed to service elevators, through kitchens etc because of what seemed to be a "commercial" looking rig.
LOL ... I played a wedding cocktail reception at this upscale Country Club in Long Island NY ... got there real early to set up, parked in the front, took my gear in the front door and placed it in the lobby ... there was NOBODY in the place but the manager went ballistic when she saw I went through the front door ! ... told me in no uncertain terms that I'd better make sure I went out through the back ...
Having played in a 'wedding band' most of my career I would say I've entered through the kitchen on about 95% of my gigs ...
