I am shaky on the "or", I am the same with most words that include "or". My boss is very toxic, he constantly belittles me for my stuttering \(makes passive aggressive jokes towards it, tries to finish off my words, and even getting mad when I stutter on certain words\), so talking to him is out of the picture. As for using other phrases, I can try the "hi what can I get for you" but the word "can" may be a struggle for me as I have had trouble with that word in the past. It's just quite annoying considering I have been able to say "order" every day for the past 2 years \- its affecting my hours at work \(getting little hours now due to it\), so I need to try resolve the problem. I really appreciate the suggestions.
