with a friendly chat. We all like a drink in this business, you could begin - does the employee ever think he
has one too many? Most people
will deny this, either because it's

If the employee admits to having a problem, be as sympathetic as possible and ask if there's any help you can provide. Genuine alcoholics really don't have a long-term future as off-licence managers, but people who want to nip a problem in the bud can seek expert counselling. You might not be in a position to fund this, but you may be able to allow some time off.
More and more businesses are introducing alcohol policies in the workplace. Equipment is available to test the breath or saliva of employees for alcohol, but this can only be done if it's enshrined in a mutually agreed contract - and even then random testing can be regarded as a breach of trust and result in claims for constructive dismissal.
Alcohol testing is clearly an important procedure in dangerous occupations but has some obvious drawbacks in a profession which involves routine tasting. You're better off having a simple clause in employee contracts, requiring moderation and sobriety on the job, but not a zero-tolerance approach.
If your employee continues to give you problems, you may have to go down the disciplinary path on straightforward misconduct terms - for example, if you felt he was rude to customers or uncooperative towards you - rather than to make overt and ultimately impossible to prove claims about his drinking habits.
