‘I refuse to join any club that would have me as a member.’
If you have membership of a private club don’t ever boast about it. If you are inviting guests, be aware that they may not know what to expect and keep them informed; are ladies permitted? Is there a dress code? Accompany them into the club or meet them at the door so you can sign them in. If you are a visitor yourself respect the club’s codes of conduct. Dress appropriately and, as a general rule, don’t tip the staff.
