It's really unfortunate, if the lady said with smile or sincere attitude, my impression could be have been different.
I learned there. The customer service is the attitude. It is OK not to have things I wanted.
It is the attitude which makes the difference.
I will never come back to this place. Probably when I miss their coffee, I might go back once or twice, but other than that, I would feel uncomfortable there.
They are probably too confident about their coffee. Let's see how they will do.
After that, I stopped by bakery where the service is friendly and sincere. I still had coffee from that shop in my hand. I bought a melon flavored bread. They asked me if I wanted to have that in the cafe area. I asked " I still have this coffee, so shouldn't be here, could I ? " The shop owner said, " mmm, you have to take it out. " That was totally fine with me. He was kind and said it very friendly. It showed his policy of the shop with warm attitude.
I smiled and left the shop and ate the bread at home with the cafe latte.
This shop, I will always come back !
Am I too strict ? I would love to hear your comments. Isn't it scary ? Just one interaction with a customer loses a customer. I should learn from this.
