I've just murdered a whole village with joy this evening by needlessly, just for the shits and giggles taking my disease ridden, super-spreading 7 year old to TWO supermarkets just for the excitement of a fun packed outing for him. We didn't need to use the theme park style queue, but I pointed out that it proved that the supermarket is fun 
Expensive error... we took out a whole care home by buying Top Trumps, 2 big water guns, comics (and Runners World for me all that panting and BREATHING) ice creams, chocolate and cream cakes.
Then just to infect a whole hospital, by the time our RECKLESS retail binge was over, we joined the queue for a McDrive Thru which was no worse than on real Sundays at 10:15 am.
Bless him, he really enjoyed it. He was genuinely excited by the outing and proudly telling the cashiers about how long it is since he'd been in. At the payment window at McDonalds he asked how they know to give which food to which car, and the chap pointed to his camera screens for him. I'd already dealt a fatal blow to a teacher by good naturedly bantering if all cars had been kerbing their cars. (When it was modified a year ago they left it a bit tight, and with the queuing spiral there's no space to swing wide to avoid them... I was relieved that the Ford Ka in front of me failed to as I have a people carrier. The 4x4 behind did it too so I'm vindicated that it's not just me
)
I'd forgotten that last time he went to the supermarket, probably around February, he'd been doing money at school and was totally THRILLED to discover PRICES on the shelves for ALL the items. Then the prices were all printed on the RECIEPT! The reciept of my week's shop was then taken to school to share this amazing discovery for show and tell. He got Star of the Week for his excitement about it 
I think I need him for a patronus as he is just such a sunny and cheerful soul.
