The tour guide (not to decide) on promotion and advertizing of new tours. What you (to do) now? We (to make) a tour of Europe last year. Our customers (to attend) the exhibition tomorrow? When they came the banquet already (to begin). Sometimes this travel agency (to sell) separate services. The ticket agent (to work) on the computer now. When Columbus (to discover) America? She (to work) on the computer at that time yesterday. You ever (to be) to a luxury restaurant?
