You aren't paid very much above minimum wage. At all.
You will be working hard. A lot is required of you, and customers wont be impressed with a casual product knowledge. If you're not already a Lego nut, you will be.
You are scheduled to be in various parts of the store at set times in the day, often if a manager is rota'd to be on shop floor, they'll decide to work in the back room (or watch youtube videos instead) so you may need to cover multiple areas on shop floor.
You are assessed in a variety of ways, mystery shoppers, online feedback surveys - although doing well is often rewarded.
You can get quite a lot of difficult customers, especially around Christmas time, who ask the impossible, some of which have been known to leave bad online feedback, knowing how much it can damage staff.
Time off needs to be booked upwards of 4 weeks in advance. You can automatically be given extra shifts in holiday periods without notice, so book off time, even if you don't think you'll be scheduled to work anyway.
Be careful around management. They don't always do things by the book, but that doesn't mean they think it's okay from employees.
