Unless you like chaos and crowds like it's the last day before Christmas, I'd suggest visiting when…read moreit first opens in the morning. Don't bother any other time. Nothing is that urgent unless it's for the pharmacy. Another Yelper called it a madhouse, and I'd agree.
Also, there are so many folks ordering food that if you're Deaf, you'd better tell them your number or you're screwed.
Of course, I'm from the mainland, so my take is specific to me. However, regardless of the crowds and chaos, for the majority Puerto Ricans still manage to be polite and friendly, and maybe it's merely an island attitude, one of which i encountered living in Hawaii and the Philippines too.
Also, back home, we'd have a maximum of ten customers waiting on food Monday through Friday. It's just not as busy as it is here, and i don't think any of those i have visited can compare to this location- not Lexington, Florence, Toledo, Indianapolis, not even Los Angeles.
I got petrol at this Costco when it first opened without any issues. Pretty quick process, and these folks don't mind pumping on the other side of the station, and back home, people refuse to pump on the opposite side. Yet the hoses can extend to the opposite side, making the process quicker; so, at least here in PR, they understand it.
They did have several pastries that i wasn't familiar with back on the mainland, as well as several juices; so i decided to purchase them.
