3 guests came from shanghai

yesterday we received guests from shanghai EATON , they were 3 people, one of them is very skilled at talking ,one of them is very kind and upright, there is a very young people in his late twenties. We planed to pick them in airport around 10:00 a.m. ,but because of the heavy fog in the morning ,the plane was delayed, and they arrived at our company about 2 hours later than the scheduled timetable. before they went to our company ,we went to a little restaurant , I made a mistake during the lunch by permitting our guests paying the bill, I were blamed for it later when our manager knew it. In the evening ,we invited our guests to a hotel to have a dinner , the hotel is new-built establishment near my place, the food here is very expensive ,and the bill was a big number ,and this time we implemented our responsibility,we paid the bill. we drank white wine, we smoke, after the supper ,I felt uncomfortable, but I had to do it in order to show our hospitality. :-(
today it is rainy, I accompanied two of our guests to two local scenic spots ,after that we had our dinner , and then we sent them to the airport about 2 hours before the airplane was scheduled to take off .
