On arrival we found that the lounge was short staffed, had ran out of snacks, crisps, cakes and cold soft drinks, which where waiting to be refilled. We where in the lounge for approximately 90 minutes in which the 2 members of staff where run off there feet managing to serve the ques of people at the bar, and struggled to collect dirty glasses and refill the snack area and soft drinks. We personally have visited several executive lounges in the past but have never came across this problem. Would recommend more staff especially as the lounge was fully booked, As the amount of customers was known in advance, there should of been more than 2 staff available. Please note the staff where polite and accommodating as humanly possible in this situation.
