You guys have NO idea how much beer you'd get if that Pub you visit so much had a PayPal link to "donate money towards the empeg, ltd. staff"

Naah, go to the web site, get the phone number, ring the landlord, and give him your credit card number to buy them a round. I've done it a few times and the landlord is scrupulously honest about it. Go on, give it a try. Remember the opening times of British pubs and the timezone differences, though - I doubt they would appreciate being woken in the middle of the night...
