what's wrong

Working today alone, i mean working as the highest person in the restaurant just now. And its was so dam boring, silent almost for an hour. Its was about 6 plus in the afternoon and its was like a ghost town. Notices something wasn't right i asked my co-worker to look around the places to see where are the customers . But as result show, the whole Singapore flyer was like a ghost town. Anyway, the crowed reappeared and we are back in the business
