Input: So, tonight I went to the local shop to pick up a few beers to chill in front of the TV with once I finished work. Its a 5 minute walk to the shop and I left 12 minutes before the shop closed.

Before I continue; I work for a startup and required hours can vary, if things need to be done then they've gotta be done, especially if it's some sort of emergency, so tonight I worked almost 5 hours (unpaid) overtime and when I finished fancied a drink, only the pubs were closing soon so I might only get one in before I have to o to home, so went to the shop. 

I get to the shop, and as I'm about to open the door the owner (at least I think he's the owner, he's there the majority of the time) opens the door, about to walk out. I smile, say hi and walk in just after he comes out. I believe he also smiles to seemingly acknowledge me (with me being a regular to the shop, we always say hi, how are you, the usual formalities etc.). Now just as I'm walking in he says (in a very annoyed tone - he's usually super friendly) "cmon man, I'm shutting it down now, be quick". I look at the clock on the shop, thinking I must've made a mistake, I am going to (and always do) spend a couple of minutes here, if that because I know where everything is in that shop like the back of my hand and he also must know that - however the clock on the wall says 10:35, 5 minutes past closing... I apologise, take a few beers to the till and pay, he doesn't seem happy at all, the most annoyed I've seen him in 3 years of going to the shop and I now feel bad.

When I get home however I check the clock on my phone (which I know is accurate) says it's 10:32. Meaning I must've left at 10:27, latest (I had a cigarette on the way home so walked slower than I normally would and took a minute or so to finish it before I opened the front door and came in).

I don't really like any confrontation, am always as polite as I can be and hate to annoy/be a pain in the ass for anyone else. So, AITA here? Should I have not turned up at the shop 5-8 minutes before the shop closed and just gone without tonight, knowing I would only take a minute or two at most? Or do you think he was maybe just having a shitty day?
