I don't know about in the bride's and groom's cultures, but in the US, "and guest" is of rather recent vintage and not at all expected by etiquette. If the person is in a serious relationship, the other half of the relationship should get their own invitation (unless they are co-habiting, in which case they share an invitation, but the invitation would have both names on it, not "Mr. One Name And Guest" but "Ms. One Name and Mr. Other Name" or whatever). If the person is not in a serious relationship, "and guest" can be a nice courtesy, but is not required. The person supposedly shouldn't be lonely because if none of the single people were invited with guests, they can mix and mingle with one another, plus some of them probably are already friends or relatives with one another anyway.
