Working in retail should be mandatory for everyone, as it gave me multiple skills which I use even now:
-Customer Service skills
-How to problem solve and work with money
-And how to learn more about the city of which you live in, as many GT's can be the heart of a community.
Depending on what position you are in, you'll have different tasks.
-Bagging items, counting money, processing returns, refilling bags
-Putting away stock, assisting customers with questions, knowledge of layout of the store.
More than anything the job NEEDS you to be friendly and have great customer service skills, which most people will accumulate naturally while working here.
Great starting job
No room for advancement, angry customers
