I have worked at a number of restaurants throughout my career in London and Milos was by far the worst. It represents all the bad connotations you associate with working in restaurants - long hours, lack of breaks, stress, being badly treated by your seniors, poor career prospects and instability. The restaurant industry in London has evolved from this and it does not need to be this way. It isn't difficult to look after your staff and treat them well, yet still maintain a successful business.
While I worked at Milos I witnessed people working incredibly long hours - 80/90 hours a week at times and for 6 days in a row with one day off. You weren't just expected to do this, it was a requirement. Lots of restaurants experience this when they open but there was very little acknowledgement of this situation or the hard work and it was much the same 6 months after opening.
Staff were fired unnecessarily and without the opportunity to improve or learn from their mistakes - sometimes 10 people a week. It would be understandable within the first few weeks of opening if they weren't the right fit, but staff members were fired on the spot, right in the middle of service at times, for doing little more than getting on the owner's nerves or because he felt like it. It made the atmosphere in the restaurant tense and uncertain. There was a complete lack of empathy for people's situations or the fact that the staff had lives, families and homes to pay for.
