Devon retailer Lesley Brown has expressed her pride after staff members passed the Award in Responsible Alcohol Retailing.
To gain the award, employees need to read a handbook which deals with topics including how to deal with underage or drunk customers and acceptable forms of proof of age. They then complete a questionnaire over the phone.
Lesley, who owns Frank-marsh Store in Barnstaple, said: "We are very proud of the interest from our staff and the results they achieved - particularly as we are the first store in the area to take the qualification."
