If at a LS club, husband will approach you to gauge your interest, which is sign she's looking. If wife is feeling "froggy," she'll waltz right up and ask directly if the BM is interested in joining us at our table - pretty direct. If via online, we make it obvious from the first communication. Other things like anklets, toe ring on second toe, etc. are unreliable. Wife wore anklets LONG before in this LS. Now, if anklet has QoS charm, BBC charm, or a HW charm, it's pretty self-evident. Plus, when wife is IN the LS, would contend the couple are ALWAYS looking unless they are playing exclusively with just one BM. Point is, the direct approach is what we use because it keeps down the confusion!
