There was a thread earlier in the week about kids in trolleys in supermarket. I admit I was rather naughty and my wit got the better of me BUT in my defence there were a few egging me on ;)
Anyhoo I used a SN trolley this week and it was awful!! Like trying to push a bus! The man stared at me when I grabbed it and strapped dd2 in it and we did get some funny looks 
Dd was facing me so was nice to be able to chat to her and she enjoyed it.
I was going to update other thread but its gone
