You identify three main customer groups that come to alexandria. which one will you use social media to connect with first?

I would use social media to connect with those who actively use social media daily. When people come into a new store, there are usually information sheets at the front to allow the store to know how they were referred, if the mention social media, that would be the first way I would try and engage these customers in the future. If they do not use social media, I would consider a different way to connect with these customers.
