The session was purchased online for 3 hours prior to actual departure time. On arrival at 2.15pm a large queue was waiting some of which were people paying at the time. I was informed that it was very busy and seats may not be available which was true for the first 30mins. I took a seat at the bar to wait and was rudely told I was not allowed to sit there by the barman. I paid a further 20 pound for a shower which was actual a good experience and when I had finished found a seat and sat for about 45 mins before making my way to the gate for departure. As a value for money experience I would not recommend it as by total value I would just sit and order a cooked meal at one of the terminals restaurants in future. In essence the lounge is small, clearly overbooked and the staff due to obvious pressure of many customers come across as rude and unsympathetic.
