“she had to be carried down the stairs afterward to use the bathroom”
I’m a little confused by this. Did the nightclub have an elevator or something? Otherwise how did she plan to tackle the stairs even if they hadn’t pushed her wheelchair down them?
The young lady’s chair was empty because she had been carried downstairs to use the bathroom. The perp is a trouble-maker.
The unknowing or uninitiated are amazed at what can be done by an experienced user. I may be a 69-year old paraplegic who cannot stand upright or walk unassisted, but due to the grace of God, I still have limited use of a few muscles in my legs, allowing me to climb stairs while death-gripping two handrails. I can go down stairs in my chair, backwards; gangways to floating docks too. If you don’t learn to adapt, life gets very hopeless, very quickly.
