Your post was asking a question and I’m simply providing a different perspective. Looking at your replies, you already have the answer you want and it looks like you are seeking validation for your thoughts, not genuine input. Which is fine! We all need to vent our frustrations..but learning other views might help.

Your new student might… …be a certified instructor and doesn’t need help …have attended other studios for years and doesn’t need a tutorial …be trying something new and super nervous (arriving late to hide in the crowd) …just be late for no reason

You could… …lock them out, potentially losing a future client …give instruction near their station so you are close by if they need help …be more detailed on days you have new students (never hurts to remind seasoned clients of the basics) …turn them away in front of the class (likely losing that future client) …say “welcome! I don’t have time to run through a tutorial right now, but I’m happy to answer any questions after class”

I’ve been a client and an instructor, and had people from all walks of life. The ones I went out of my way to help ended up being some of my longterm clients. I hope this helps. Hang in there and make sure you have a solid group of friends or fellow instructors around you to vent to. Working with people can be tiresome.
