Pão Fôfo — Restaurant in Porto

We found this bakery on our first day in Porto, and it became our go to place for afternoon tea and pastries. The food is very good, fairly priced, and quite delicious. The bakery is very busy and the service suffers for it, especially the hospitality... since the waiters come across a bit terse. Until yesterday, I would have rated it 4 stars, but yesterday's experience dropped it to 3 (and maybe even 2) stars because of their attitude. We usually order tea, lattes, and several pastries. Yesterday, I asked for some more hot water after finishing my tea and was refused. The waiter actually said he would charge me for the additional hot water which hadn't been the case the previous days and in any other bakery or restaurant that we've visited. I mentioned this casually as feedback to the manager as we were paying and he just shrugged. By the way, I speak fluent Portuguese, so the interactions were...

I commanded for a coffee a pedras and a nata , then i was served , after 2 min i asked gently to change the pedras to a lemon one ( i didnt opened the bottle ), the waiter changed the tone and started blaming me like i asked him to deplace a mountain he said that the bottle is less colder and i have to ask for it in the beginning then i said i dont need that give me the previous bottle then he stopped directly , i would said to this waiter that he has a lack of education and professionalism...

The food was good, but the service was disappointing. Staff didn’t speak English, and I waited at the counter for a long time to order, no one didn’t care to help even if I asked. There were no price tags or food names displayed, and one lady responded quite rudely when I asked about ordering. Thankfully, another staff member with short hair helped us just before we left, which I appreciated. The cappuccino was nice, though it tasted a bit like it was made...
