There I am, wandering around the plant section with my friend. I'm knackered today, having had 2 hours sleep, and I yawned with my hand over my mouth, not making a noise.
A lady was opposite me in the aisle and came over with her big trolly and said to me "other people are shopping here, you know"
I thought I was blocking something she wanted to get to and said "oh sorry I'll move" and I did move, to which she replied "no for gods sake, I meant about the yawning. Can you not save that for at home"
I laughed, she tutted at her husband/partner/male friend and then they both flounced away!
So, AIBU for yawning discreetly in IKEA?
