The case: Jim is preparing a huge party for his wife's birthday. He contacted a caterer over the phone and explained to him what he needed in terms of food and number of guests. Jim made it clear that he would like the food to be delivered on Saturday, 14th at 4.00 pm. The caterer has agreed to all Jim's terms. They have also agreed on the price to be paid upon delivery. After the phone call, the caterer has sent to Jim an email summarizing all the terms of agreement including the date of delivery and the price. On Friday 13th, Jim knew that he will not be available on Saturday 14h due to urgent business commitments, and therefore he will not be able to organize his wife's birthday on that day. He called the caterer again and asked him if he can change the date of the delivery to Sunday, 15th one day later) and explained his reasons. The caterer seemed annoyed. He explained to Jim that he has already made a lot of preparations that might expire within 48 hours and that would mean extra-work and extra-costs for him. Jim insisted on his request and the caterer ended up by making a promise to Jim to deliver on Sunday 15" instead of Saturday 14h. On Saturday 14th, Jim's wife was surprised to receive at her door a huge food delivery. The caterer crew was there delivering Jim's order and requesting payment. Questions: A.
