I made reservations for my b/f and I for all of my adr's. My sister live in florida and my want to join us for a meal. She is the type of person that can't keep a date so my question is if i stick with the adr's for 2 and she decides an hour before that she wants to come with us do the restaruants ever turn you away if you show up with an extra person? And if i make them for 3 will they turn us away if she doesn't show up? What would be the better option to do????
