Does changing perspective mean I cannot raise concerns about poor service?

You can raise concerns. Learning to change perspective and understand the other person does not mean simply tolerating inappropriate service. You can still explain what was uncomfortable and let them know where the problem lies.

Miao Nian shared an experience of taking her mother to a restaurant for a birthday celebration. A server put the dishes down heavily, left the plates crooked, and walked away. She later spoke to the supervisor. Her point was that even if the server’s hand had slipped or the heavy placement was accidental, they could have said something and apologized instead of leaving as though nothing happened. She wanted them to understand what had not been done well and hoped later customers would not have the same unpleasant experience.

The server later apologized, then helped sing the birthday song and take photographs, with a changed attitude. Miao Nian noticed this adjustment and specifically thanked the server afterwards. She voiced the problem that needed raising while also acknowledging the later change. This shows that mutual respect does not mean one side merely enduring things. It means remaining willing to treat each other well after clearly addressing the issue.
