My local places are pretty good. My biggest beef with most LDS and charters is the fact that they rely on Facebook for everything. Whats your class schedule? "Check facebook". Trips? "check facebook"....Many people, including me, do not use facebook. .
But you don't have to actively use Facebook to see the shop's schedule on Facebook. It's not different than just looking at a website. It's perfectly reasonable for the shop to post its schedule on their Facebook page and then tell you, when you ask where their schedule is, that it's on Facebook. The nice thing about this is once they tell you where they post it, you know where it is... forever. And you can look at it whenever you want.
If you want someone to sit down with you and personally read you the class schedule, as if it's a bedtime story, you might want to consider that your definition of "customer service" might be a little different than that of the average person.
It gets harder and harder every day to book classes or trips the normal way. Have they all just gotten too lazy to actually interact with humans? Do people really book classes on Facebook without talking to potential instructors first? No thanks.
Booking things via the internet has been the "normal way" for just about everything for a long time now. There's nothing stopping you from looking at the schedule (on Facebook), talking to your potential instructor, and then booking the class online.
If you would complain about something so simple as this, as an instructor I would have to consider what else you would complain about during the class.
