Give them an inch & they take a mile.
The thin edge of the wedge. Once it is in then the hammering starts.

Till it is ridiculous.

I don't smoke & I don't mind if others want to.
But here smoking is banned in public places & within 4 metres of doorways & even in hotel bar rooms. Drinking inside, smoking & drinking out in the beer garden.
I can order a meal over the bar & eat it in the dining room or sitting at the bar, but not in the beer garden. The law forbids me to eat in a designated smoking area.
So not just a smoking law but an eating law riding on its back.

This is the sort of nonsensical thing you have to put up with when you let the left off the leash.
