I'm about to start working for myself and cannot quite afford office space right now and kids make too much noise at home to make the calls I need to.. So, I'm planning on working from the local Costa coffee - prob 3 times a week for around 3 hours a time. Will probably use the iPad and Skype to make the calls. Question is, do you think this is acceptable or will the manager take exception? Anyone else work out of a coffee shop?! Thanks.. Rob.
