we arrived at terminal 2 executive lounge at 4am on 01.07.16 as we were booked in from 4am for 3 hrs, but were leaving at 6 for our flight. upon arriving at 4am, there was only 1 member of staff on duty having to deal with check in, serving drinks, cooking hot food etc. we had to wait until almost 4.30 to eventually be checked in as a new system was not accepting certain customers confirmations , When we finally got in, we were then told to help ourselves to the cold food or hot drinks. we could not get a drink from the bar and there was no hot food at this time. around 4.45, the guy checking in left his post to serve a growing crowd at the bar. he reassured folk that bacon barms were coming, as they were in the microwave. they arrived at 5am, and soon were gone with a queue waiting for more. mess was amassing on tables, people did complain to the server, who clearly was doing his best as he explained staff had not turned up, and help was on the way. it eventually did, and by 5.45am, normal service was under way. unfortunately a very poor start to our holiday.
