Rayray: nope - it wasn't Hills & Parkes - so you're (sort of) off the hook from me.
Like I said in my original post, I can appreciate that it's difficult if you have a youngster asleep in a buggy and you need to go shopping.
But I still maintain there has to be a bit of give and take, especially when the total floorspace in the shop(s) in question is only marginally bigger than the footprint of the buggy that you're driving.
An apology to the other customers in the shop for any inconvenience caused surely is the minimum that anyone would expect. The Trendy Daddy in the shop in my instance seemed to think that he (and his buggy) was the only customer of importance...
