Wimpy Pretoriuskop service failure

At Pretoriuskop in KNP. We were eating there our last night 12/12/2021 before we go back home the next day. A treat for my family. Suddenly while we were eating the lights was switched off and all the staff went sitting outside just after 20h00. We finished eating in a hurry because it seems like they are closing now. The 10 year old child was getting scared. The exit door was partially closed and when we got outside I asked them about closing time because at reception when we booked in they said Wimpy's closing time is 21h00. So the guy that served on us said...if there is no customers they are locking early...I asked him...so what are we? He could not even answer me. This was a serious bad experience and I regret taking my family to that Wimpy🥺 could have rather got something from the shop.
