Worried now...
I was shopping today in a well known not very nice supermarket. There was a woman standing looking at some stuff and I needed to get past. There was plenty of room in front of her so I walked through the gap and said sorry, to which she responded "bloody hell".
I responded that I'd said sorry and she said I should have walked behind her.
Have I had my supermarket etiquette wrong all along? Please tell me if I was rude here.
