Переведите текст с настоящего времени в прошедшее I spend a lot of time at the college, that is why...

I spent a lot of time at the college, that is why it was necessary to have a snack time there. During the break I went to have lunch at our college canteen. It was always full of people at that time, so I went to the service counter and lined up. There was self-service at our canteen. Sometimes it took quite a lot of time to stand in the line and I had to gulp my lunch in five minutes. The choice of dishes in our canteen was rather rich, the quality of food was good, and the prices were reasonable. To begin with, I usually had some salad — tomato and cucumber salad or mixed salad. For the first course I had soup — fresh cabbage shchee, solyanka, pea soup or maybe some fish soup for a change. For the main course I had meat or chicken dishes, for example steak, meatballs or roast chicken with spaghetti or potatoes (mashed or fried). For dessert I usually had fruit juice or a cup of tea with a bun. I took them from the counter, put on my tray and went to the cashier's desk to pay the money. Then I took a seat at any vacant table. Besides the kitchen staff and the cashier, two or three students on duty helped to clear the plates and cups off the tables and to keep order in the canteen.
