I’m not so sure…I'm sure it's deliberate, I have seem similar. I politely laughed and mentioned I had some yellow balls of same make in the bag, I can swap if they were "having identification issues." My playing partner who was twice my size said something less "sociable!"
Don't rise to it, but make sure they know you know it's deliberate. Maybe that club needs to be having a fixture removed from the calendar?
As mentioned, I have been tripped up by the same in the past. At the time I thought it deliberate…but on reflection I very much doubt it…coming to believe that they themselves had a bit of a brain fade, and didn’t realise they were standing by our ball until they came to play and immediately spotted they were by our ball.
Apart from anything else, for me it’s very much better to forgive than hold a resentment. But though I put the incident behind me I don’t just forget and so I remember to check my own ball as that is my responsibility, not my opponents.
