to want to find a cupcake shop and buy a shop across the street.

Then I would have a big sign made up that said, 'Oh fucking grow up' in sight of all the customers as they leave and of the shop owner while they go about their day.

YANBU The kids occasionally blackmail me into buying them and
a) the cost!
b) the mess!
c) they leave half of them because they're not actually very nice, which wouldn't be so annoying if it were not for point a) above.
