Yes this is rather common in the corporate world and in my line of business. I guess I worded my question poorly because so many people responded with what I should tell the person who is offering this gesture what to do and how they should pay for my meal.
I was really looking if anyone knew how to call a restaurant directly or if anyone has done this at a particular restaurant. I can see from my original post how this may have been confusing however I didn’t want to get into discussing how my line of business works everyone so I just read everyone’s thoughts understanding they were trying to be helpful
as I said STK has a process to get this done, not my first choice but I am CERTAINLY appreciative of the person for even offering even if it doesn’t work out
