Recently, I was wanting a jar of seedless strawberry jam for my grandson's toast. Shopping in M&S (very new store and very busy where I live) I went back to get it three times as there was an elderly couple (at least 20 yrs older than me) standing, blocking the shelves. They each had a trolley (both practically empty) - possibly using them as walking aids, and they took up a good proportion of the aisle. I did not say excuse me as I thought they would move on eventually and I would double back for the jam.
In the end I had carried on shopping and I forgot to go back and went home without the jam, which made my grandson cry the following morning as it's one of the only things he'll eat (jam on toast/jam sandwich) for breakfast. He refused all other breakfast suggestions (wouldn't have toast, doesn't like butter, wouldn't have dry toast) and went to school hungry.
I wouldn't dream of 'shifting' people out of the way - they were there first and will occupy the space for as long as they need to. I always accommodate those who are 'in front of me/get there before me'. I remember complaining of having to wait for something when I was very little and my grandmother viciously snapped (I remember her spitting in my face during the telling off) 'well get up earlier and be first then' which made me cry - very vivid memory of crying but not why we were held up/waiting. I remember feeling full of shame for complaining.
My husband, on the other hand, would have 'shifted' them by barging through and reaching in front of their faces for what he wanted. He would not have said excuse me. That approach would not have resulted in my grandson's tears - happy grandson, having had breakfast before school.
I think OP was rude - H would not think OP was rude.
One POV cancels the other so no point in me posting - other than it reminded me of upsetting my grandson last week.
He only eats cheese squares on toast for dinner and luckily, I had some in the fridge for home time. I now have strawberry jam and will not run out of it in future - one open, one spare. (Usually only have cherry jam and lime marmalade.)
His safe foods rarely change, but had changed during half term. I need more notice next time - and a slightly better memory. Could have kicked myself for forgetting the bloody jam.
If only H would do the shopping all the time .... and shove all the old people out of the way.
