I work at ASDA (days) but my other half used to work nights. Its over Â£8 an hr and working nights everyone becomes a real community as there aren't really many customers about so you can have a laugh.y dream job at the moment is to work at ASDA preferably at George. ASDA is one of the best places around with products that represent a great value for money. They also sell great chocolate/cookies. Best supermarket chain around by a clear mile.
