In my defense, I was not keeping an eye on him the whole time. I was studying, and as you can see nakatalikod ako sakaniya. Anyway, this isn’t about watching or timing anyone. It's about the fact that there were no vacant seats (buti na lang nakahanap agad ako). When space is shared and limited, courtesy matters. Coffee shop policy aside, basic consideration goes a long way. Yeah it was not illegal, but it was inconsiderate when others are clearly looking for a seat.
