For a while now, coffee shops have become little offices for those of us who have no fixed work abode. Being able to meet people in a neutral location is also useful, and having fresh hot coffee is a real bonus.
There are unspoken rules, though, for places like this, and it seems as if this customer is breaking them. You have to realize that other people are using the space and act accordingly. Meaning headphones, indoor voices and not taking up too much space. No-one else wants to hear what you’re telling your agent.
