How to pimp up your pint of Guinness (in the wrong glass)

One of the major side effects of the ongoing crisis is I can't go to the pub, and that means I can't have the only type of Guinness that's acceptable to have: draught. HASHTAG first world problems, I know, but this is a big deal because there's a world of difference between bottled or canned Guinness and Guinness on draft. But I've found a hack. I keep the bottle of Guinness in the fridge but I put it in the freezer around 20 minutes prior to consumption, then I pour it in the (wrong) glass, which is actually a pint, and make sure it's as foamy as it can get. Then I drink it and it is almost, semi, quasi, very nearly, more or less - acceptable.
