M. X.

I reached 7 mins before closing time to buy something that it'd have taken 2 mins to get, but they said they were already closed and don't let me in. Don't set 18:00 as closing time on Sundays if you're not willing to let people in before that.

EDIT 1: Next day on Monday, I've dropped by around 17:25 and it's closed, so go figure. It's the third time I've passed by in vain this week. Stick to the working hours or change them, but don't make people waste their time.

EDIT 2: In the end, I ended up buying what I needed at Xenos.
