Earlier quoted context omitted.
Next time try calling the restaurant!
The restaurant had its name on the bill but no telephone number. Presumably, this done to stop or reduce telephone complaints direct to the restaurant. Seems that everything must be done online.
It is sad to see that prediction coming true in various fields. This strong bias against having customer service people, against customers having any way to talk to a person, is noxious to society at large.
I guess in the same line of thought, I find the abandonment of the public phone system to be sad. Instead of replacing old phones with newer terminals with internet capabilities, we abandoned the entire system. Therefore making the world a bit more unequal and a bit more dependent on personal devices.
