I'm not a prude but I was in a Patisserie Valerie cafe for afternoon tea. I was sat with my sister & the queue was forming for the till right next to us, So far, no issues.
That was until a couple in maybe their 30's/40's joined.
Right next to us the man lowered his hand and placed it under the woman's skirt! Didn't keep it there long, the woman didn't comment on it so couldn't have minded or didn't want to cause a scene.
I was too surprised and embarrassed to say anything plus I'm not sure I'd have known what to say.
I just found it totally unacceptable.
Silent treatment - son
Caught in the act - neighbours
How to say it - 'no'
