1. You never go to a pub for “just the one.”
Rounds are expected. An awkward atmosphere of mangled maths and unnecessary extra work is created when someone chooses to pay separately.
2. And you’re suspicious of anyone who orders a “half pint.”
3. You’ve indulged in a pint of Real Ale.
It’s flat, warm, and bitter. If you know what’s good for you, you’ll enjoy it.
