Cracker Barrel complaint: Seating

I am a regular customer that dines there every weekend and sometimes during the week in the evening. My husband and my young grandson met me there to eat dinner about a week before Christmas. Before I arrived the woman that was sitting guest which her name is Lyanna, which is a shift manger was very rude to my husband. We asked for a special server Mowana. She stated she didn’t have and tables for 3. At this point my grandson thought it was he fault that we couldn’t be seated. So now he is in tears and upset. Was looking forward to pancakes. My question is why couldn’t she just pull a chair up to a table. Instead she told us that it was going to be a while and that we could have the table that has six chairs. Which she just sat that party to right before us. So now we were looking at a long wait. My husband asked to see a manager and she snapped back and said I’m the manager. She was very rude. I was going to just let this slide but just the past weekend I told my husband I was going to breakfast the next morning and my grandson had stayed the night and popped up and said can he come. I Said yes, and he popped up and said where. I told him Cracker Barrel. His reply was never mind he will stay with his papa. That’s pretty said for a 8 year old to worry and feel like it was his fault. So now my husband and grandson refuse to step foot in your restraunt and I can’t blame them one bit.
