I have NOT done that. If I am going there anyway then why bother giving them my info? Also, the ordering kiosks are good in the store for people who don't want to talk to anybody, the only drawback is the people who bring the food are too dumb to bring your cup so you have to ask them for it anyway.
I haven't but I've been thinking about it. So I'll be curious as to everyone's responses to your question as well :-)
