There are times when you arrive at the location, and you are asked to do other work. For example, you have been accepted for a gig in waitressing, but then they need you to do the dishes. In such a situation, it is best to discuss this with your client. In principle, you have not been hired to work in dishwashing and you may decline the job. 

However, keep in mind that this may affect your evaluation, and you will probably score more points if you show flexibility! If you are not qualified to do other types of work, it is recommended to find a suitable solution with your client. If you can't work it out together, it's best to contact us, and we can see what we can do for you.
