Sounds like it was a big disappointment. Sorry to hear that. Since you booked a hotel room, can you go back to the store today to buy stuff?
I would love to go to their store.
Was it a Christmas party for everyone (customers) or a staff party and you were specially invited?
Maybe send them an e-mail and thank them for the invite but express your disappointment. Maybe they have no idea what people were hoping for. I bet of they knew they could of made sales that night, they would keep the store open next year.
Did you take any pics? I would love to see their company. Always curious if it is a smaller operation or massive. I would love a job there.
