Final answer:
The decision to serve wine by the glass and whether to charge a corkage fee are based on the policies of the specific establishment. Serving wine by the glass is common, allowing for variety without the commitment to a full bottle. A corkage fee is for when customers bring their own bottle and covers service and glassware.
Step-by-step explanation:
In a hospitality or restaurant setting, the choice to serve wine by the glass and whether to charge a corkage fee are important considerations. Serving wine by the glass is a common practice that allows customers to enjoy a variety of wines without committing to a full bottle.
When a customer brings their own bottle, a corkage fee is typically charged. This fee covers the service and use of glassware provided by the establishment.
As per the options provided, if the establishment does serve wine by the glass and charges a corkage fee, the correct answer would be option a. If it serves wine by the glass but does not charge a corkage fee, the correct answer would be option b.
If it does not serve wine by the glass at all, the correct response would be option c. Option d appears to be unrelated to the question. However, without specific details about the establishment in question, we cannot definitively provide the correct answer.
