The Flying Horse / Re-Read of The Cuckoo's Calling

So I'm listening to the Audiobooks for the first time and this line stood out to me this go around. It's when Strike has found out that Charlotte is marrying Jagi and gets drunk and goes to The Tottenham:

... it was empty but for one other drinker; an old man just inside the door. Strike bought a pint of Doom Bar and sat down on one of the low red leather seats against the wall,...

I visited London this summer and of course had to stop in to The Flying Horse. I didn't see any Doom Bar on tap, unfortunately,but I did run into an old man who was sitting just inside the door. We talked for a bit as I sat near the bar and he said he'd been drinking there for like 60 years or something. It was interesting interaction until he asked if I had a boyfriend, lol, but yeah, this line reminded me of him. Probably a coincidence, but it did make me wonder!
