Ellen works at a golf course. During the summer, she drives a golf cart around the course, selling cold drinks and snacks to the golfers. It's a beautiful day, and the course is especially crowded. Ellen offers one golfer a cold drink, and she replies, 'Well, I guess I'll have time, since the play is so slow. It's not very fun to have to wait so long between holes. Who is running this course? You always set your tee times way too close together!' Ellen's customer is a(n) _________ customer.
