I don’t get one old ppl joke

[u/Educational-Leg1402]

I work part time at Migros and only in the last 2 days 3 elderly ppl were joking about needing the receipt for the tax declaration. I don’t get the joke😭 all of them said it jokingly but whenever I made an hypothesis the next one falsified it, so can anyone here explain what’s the deal plz? Thanks guys
