So I'm in the supermarket with my 4 year old & 19 month old whom I have to strap down into a pram because he's a runner & is heavy. I normally shop online but I needed to nip in for a few bits, ie a small baskets worth of stuff. if you 'nip' in anywhere with 2 kids in tow Anyway, I'm stood there minding my own business and the old guy behind me looks me up and down like I've just crawled out of the sewer & says 'this line is basket only,' so I said 'all I have in my trolly is my son, he's too heavy to carry & I only have a few items' but he's not happy, raising his eyebrows at me, huffing, puffing etc. I ignore. The nice girl on the till serves me but when I turn to go he starts ranting - and I mean properly ranting - to the till girl about how unfair it is I was allowed to go through, it's not on etc etc. The girl said it was fine, I'd only got a few items but he carries on ranting so I stopped & defended myself saying I've got 2 kids in tow, could he carry a baby & manage a pre-schooler round a busy store & carry a basket? He continues to rant about it not being fair so I huff off. But really - is it that much of a sin? I'm bemused! Most people give you a sympathetic smile when you're going round a supermarket with kids, did I break some supermarket taboo here? AIBU?
