Back in Liverpool, his father put his son in charge of the record department of the family's newly opened NEMS music store on Great Charlotte Street. Epstein worked "day and night" at the store to make it a success, and it became one of the biggest musical retail outlets in Northern England. The Epsteins opened a second store at 12–14 Whitechapel, and Epstein was put in charge of the entire operation. He often walked across the road to the Lewis's department store (which also had a music section) where Peter Brown was employed. He watched Brown's sales technique and was impressed enough to lure him to work for NEMS with the offer of a higher salary and a commission on sales.
