They noticed three rows of tables of ten seats each and knew there's a reservation for a big group of guests.
As the group started streaming in, the man realized they are staff from his company's HR department.
Fortunately, he only knows one of the lady out of the group of almost thirty.
As these people walked to and fro getting their food, his friend noticed something.
They all looked very similar.
Their hairstyles were mostly straight and at shoulder length. Their clothes are either white, black or both. Clothing designs were similar with very little variation. Even the only printed blouse a lady was wearing was white and black. The way they walk, the way they talked and behave were also very similar.
His friend turned to the man and said jokingly "I don't think I can recognize anyone of them if I see them again. They all look so similar."
