Today, a customer complained that his earphones stopped properly functioning even though he bought them less than a month ago. After checking them, I realised that there was so much earwax caked into them that it affected the sound quality. FML
Hi everyone, OP here ! Made an account just to follow up.
1) No, sadly he didn't suspect a thing and didn't bother taking a close look at his earphones.
2) It was awkward indeed. Very, very awkward. He was nice though, he apologised and immediately left. Hopefully he'll check his earphones next time.
And thank you for commenting on my username haha !
