You know that you aren’t really welcome at your local Tesco if, upon rolling into the shop and into the spot you usually do to wait for assistance, you see one of the members of staff notice you’ve arrived and exclaim, with a hurtful mixture of resignation and contempt, “Oh, the wheelchair guy!” You then spend around ten minutes sat in that spot while you overhear the staff argue between themselves over who should help you get your shopping. I know I shouldn’t really complain as I got helped in the end, and the staff need to interrupt their other tasks to help me; but it really is draining to know I’m perceived as that much of a burden by some.
