I would guess that he was in his early 20's and seemed to be some type of a shift manager. Maybe an assistant manager, but seemed to be a pretty bright guy and very welcoming. I had gone into the "Wendy's" for an Oreo twisted frosty and he was the one that greeted me.
I decided to go into the store rather than going through the drive-thru because I had a somewhat unusual request. When I place my order I also asked for a small coke, but I wanted the cup to be full of ice and only a quarter the way filled with coke. Since I am limited with my fluid intake and chewing ice helps with my frequent thirst I find it kills 2 birds with 1 stone :)
After I over-explained my restraints on fluids and he gave his apologies of having to charge me for the full cup he decided to give me a medium cup with my request and charged me for a small. He started to turn away and then said "Only 32 ounces? how do you do it" and then grabbed a large cup and said "this is 40 ounces - this is more than a full day of fluid for you, I drink 1 of these each meal"
It has been a while since I have had that feeling. The feeling of someone actually understanding what it is like to have a limitation out of their control. People going through the limitations understand what it is like, but I have found very few people who actually get it that are not going through it - I guess it is the small things in life!!
