Occasionally there are no smiles, no conversation, and worse, no thank you for the service that you've provided. Not everyone is a happy customer. Food and beverage attendants can expect to be on their feet for extended periods of time, especially during peak trading periods. But if you'd prefer a non-desk, more physical occupation, this aspect should be viewed positively. Food and beverage attendants serve customers in establishments such as restaurants, hotels, pubs, taverns, private clubs, and banquet halls. You'll need to be at least 18 years old if you are expected to serve alcohol in any of these establishments.
