Sherie, usually I just park the trolley and go out to a seat just out the front of the shop, then go back in and resume shopping (I never put cold things in until last anyway) - easy peasy. Also necessary when you are toilet training a toddler ("Mummy I need to go to the toilet NOW!!!!!!") LOL about the walking frame speeding away!! If they don't put a seat in I might have to start taking DH's camping stool shopping with me LOL!
