However the burden of guilt became too much and last month, Mr Steinzer spent £1,000 travelling to England to try to find Pat and buy him that pint.
He went to Portishead, north Somerset, where Patrick told him he was from, and spent a week traipsing around the streets, pubs and golf courses, with a picture of his holiday friend.
But he had to return home without tracking down Pat, who was holidaying with his partner Pam when they met.
Before he went home, his quest was highlighted in the Daily Telegraph and when Mr Burns, 73, a retired advertising executive, read it in the paper he made contact with his German friend.
