2020/21 - What's made you happy today?

Went to Morrisons for the first time on a Sunday for months. Because of the queuing system at the checkout the only person I get to talk to is the checkout operator - poor chap. and its relatively quiet - enough that you can hear all the noises that the checkout makes. Every time he passed an item to be scanned it made a certain noise so I asked the chap whether it got on his nerves after a while.
He didn't know what noise I meant "What sort of noise?".
"Like a cuckoo - cook-oo, cook-oo".
So he imitated me and I started to laugh, and he started to laugh until the tears were rolling down our faces.
He actually said he'd never noticed it before but now he couldn't wait to tell all his colleagues.
I walked out of the store "crying" with people giving me sympathetic looks. To cap it all, as I reached the carpark, my till receipt blew off the trolley and skittered across the tarmac. I tried to chase after it but my trolley was going sideways and I couldn't catch up with it!!
Hope nobody was watching me as I must have looked even more ridiculous than normal.
