Why would you invite a restaurant owner for Christmas dinner?
Maybe she is a beautiful woman
I am also curious why he should invite her on a very special day, during dinner. This may be the reason. It will be a romantic dinner
Aside from that, I am quite confused that a restaurant accepts ads of cryptocurrency but they don't know about cryptocurrency.
You do not need to be surprised, it is all business deal, besides it isn't the owner who is dumbfounded but the service staff. Service staff has no say about the deals of the owner and is not a big deal if they don't know about the story behind the wall decor/ads as long as they do their assigned task and serve well.
Actually, his plan to teach the manager is good enough, at least that she knows something about cryptocurrency and will tell her boss about it... Because it is quite strange that using the decoration about crypto but don't even accept crypto.
I don't find it strange, they don't have a sign Bitcoin accepted here, did you see any? If they do have sign and the establishment does not accept Bitcoin or worst doesn't know it, then that is what we can call strange.
I think why the franchise that set the banner there doesn't even explain the restaurant about cryptocurrency and teach them so that the ads will be implemented at first in the restaurant.
It is possible that they are into negotiation, who knows, since the ads company is a cryptocurrency wallet company (stated on the earlier reply) I believe they approached the establishment and offers their service.
