Can I have some water?

I had an interesting experience today... to say the least. When I take the girls for their Selective Mutism therapy once a week, we usually drive through McDonald's on the way. The timing is easier that way. Otherwise we eat lunch too early. I rarely have a problem at the McDonald's close to us. Today was the exception. I placed our order with the drive-thru lady. I ordered a large ice water (and place my emphasis on the large). I noticed she rang up a salad dressing. When I got to the window I asked about the .20 charge. She said that was to cover my large cup. Now, I had never been charged prior to this, but that was ok with me. I understand paying for the cup. Then she said, "Just make sure they do give you the large cup." I pull up and sure enough, I see 3 small drinks. I guess I should preface this by saying that since getting pregnant, I have really not been able to drink anything other than water. Maybe some orange juice, but mostly water. Plus the drive we are getting ready for is an hour long, so I need lots of water. When the girl hands us our drinks, I said "This was a large water." She says, "Well, we only give out smalls." I said, "Well, I was charged for it and the lady back there said to make sure it was really a large." So, the girl says, "Let me go ask." She disappears and the cars are piling up behind me. She comes back and says, "Nope. I'm right and we only give out smalls and charge for the medium." I said, "Well I have been given a large every time I have come here." She replies, "Well the large would actually cost you $1.00." I am fuming at this point and said, "Ok, well then I would like my .20 refund and I will keep my small water." She disappears AGAIN and comes back with.... a large ice water. Then snottily adds, "Next time you will have to pay for this." I was SO mad! So I called tonight and talked to a manager and found out I was right! Small waters are free BUT for .20 you can get a large or medium cup water. I felt so justified and just a tad sorry for the 20 cars that were stuck behind me. You just don't mess with pregnant ladies! =)
