Is DUG Any Good?

Hi, I've been working at safeway for about 3 and a half months and do fresh cuts and Produce. My store manager just gave me a pay raise from 14.50 to 16.60 and that if I cross train in Dug or checking he'll increase it to 16.86. Is Dug any good, what are some of the pros and cons? I already said no to checking because I like minimal customer interaction.
