2)

He was reliable and punctual. When he was working in the burger van, he had to work on time. He also had to be polite to the customers. However, the job didn’t have to take much responsibility as his boss dealt with the difficult situations.

He had to get up early because the van opened at 11 am. When he wanted to, he didn’t have to take days off.

Now that he has changed to a new job, things are different. Although he likes it, it affects his life because it is a very high-pressure job, so he has to work to tight deadlines. However, he doesn’t have to work outside, which is nice.
