Bloody Mary and cocktails in a can

Susie and AJ discuss the merits of drinks in a can. They've now got used to craft beer wrapped in aluminium but think that wine in a can may be a step too far, but what about cocktails? Susie reckons that as you can get a negroni in a 100ml can now, she might put that in her toiletry bag at the airport instead of her shampoo and toothpaste as its much more useful. That aside there are many more advantages to canned cocktails, from the financial savings, to the eco advantages, the chill factor and foregoing the faff of making them. What do you think?
