to think that if your child has thrown up on the supermarket floor

[purepurple]

then you really shouldn't let them sit on the conveyor belt amongst all the shopping?
To be fair, the woman did apologise for her child spewing on the floor and she did offer to clean it up herself.
But then she plonks him down on the conyevor belt as it is moving along. Between his legs was a bottle of booze, stood up (I always lay mind down; the booze, not my kids )
The cashier had to ask het to take him down, which she did. He then disappeared into an empty checkout, totally unsupervised.
Thankfully, the woman and her sprog were behind me, so my shopping was not comtaminated.
But, eugh!

Oh, I know, and I also know that the trollies are mostly kept outside. It's a bit daft, I know.

I have a solution to ALL these problems: we nick the old ladies' wheely-trolly-bag-thingammies, put our DCs in them (could even button them up if DCs are small enough) ~ DC is contained, any unfortunate mis-hap (puke, pooh, wee, big bogies) is also contained, dog-pooh-shoes are kept away from food, old ladies won't be able to put their bags in the supermarket trollies, because we'll all be wheeling them around with us, no children will need to sit on conveyor belts, and we can have a nice sit down on them at the end of a long shop.

Where do we put the old lady trolleys as we push supermarket trolleys? Are you going to fashion some sort of attachment device and take it to Dragon's Den?

Ooh, yes habbibu! I could sing a song too like Reggae Reggae Sauce man. Hmm, will have a think about that one
