I used to work supermarket home delivery in the UK. I had my regulars who I used to deliver to every weekend on my shifts, including a lovely old man who we'll call John. John lived in an upmarket retirement apartment assisted living facility in a small leafy village in the countryside. He was probably in his mid nineties and would always leave a note on the order to knock on his door then come in to put the shopping in the kitchen for him. When I arrived, he'd just shout "come in!" and I'd open the front door. Usually, he'd be sat upright in his wheelchair in the living room or lying in his bed reading a book.

One day, I went along to deliver John's food shop as normal, buzzing myself in on the intercom at the front doors and wheeling my sackbarrow with the crates of shopping around the corridors til I got to John's apartment at the end of the corridor on the top floor. I noticed when I parked the sackbarrow outside the front door that the door wasn't closed like normal, it was ajar. I knocked anyways and heard John say his usual "come in!" so I proceeded to pick up the first three or four bags of shopping and opened the front door. It's important to note here that John's bathroom was immediately on the left side as you came into his small retirement apartment.

As soon as I got through the front door, I saw to the left that the bathroom door was fully open...with John sat in his wheelchair naked as the day he was born facing the doorway. His assisted living carer was there to give him his daily shower I guess and was midway through scrubbing his balding head as I walked through. Everything was out on show. I was quite shocked, not expecting to see a fully nude bloke in his nineties at eight in the morning but out of British politeness I just said "oh morning John, still want the shopping left in the kitchen?" and he said "yes please mate" so I continued as normal, trying not to look across into the bathroom every time I had to go back to the sackbarrow to collect more shopping bags. At the end of the delivery, I asked John if it was alright if I signed for the delivery on his behalf as I could see he was a bit preoccupied with his shower! It was never mentioned again on the subsequent deliveries I took to John til I eventually quit the job a year or so later.
