Fears of spiked drinks under ban

From the beeb:

"A mother is calling for pubs to issue smokers with plastic cups and lids in a bid to prevent their drinks from being spiked while leaving a bar to smoke.

Gillian Taylor, 37, from Livingston, is "angry" that bars are forcing smokers to leave their drink glasses unattended while they go outside for a cigarette."

Excellent idea. How about ones like this?

Observations so far: no-smoking pubs, while obviously having a healthier air-quality, stink. Smelly people, smelly toilets. Order food with that whiff floating around your nostrils? I'd rather not.
