I have some stock answers.
“How are you?” I am superfantastic. Good as any and better than many. (I got that from the late Keith Harrell who did a motivational seminar at my company back in the early 90s)
“How are you?” Great, but it is still early.
At a fancy restaurant:
My wife and I went to an upscale steak house for dinner one night. We wound up getting a free shrimp cocktail for this one. “Can I take your order?” Yes, are you still having the 2 for 1 special on tuna salad sandwiches?
I went to Chili’s one day and was greeted by the manager at the door with, “May I help you?”
Without missing a beat, I replied, “I’d like to buy some food.” What the heck else would I be doing there? LOL
I love Dave Ramsey’s classic reply to How Are You?
Better than I deserve!
