I was reluctant to post this little trick that I have used in the past.
FLL will Like this. It's called Yankee Ingenuity. When going to a wedding there is usually a Bar..sometimes OPEN..sometimes you have to pay. Either way the drinks are
watered down. I always Pay for the first drink. It's the RIGHT thing to do.
After that, I have a (Grenade Sized) Poland Springs water bottle with a pre-mixed Martini.. with which i can refill my glass. Just thinking ahead..

NB
