Most recent one was last week. We got an invite to a wedding for Aug. It had my name and guest. The bride and I have known each other for ten years, she's known my FI for the whole 5 years we've been together. She also knows we are getting married in October. Her RSVP where the postage is supposed to go, said "place stamp here", no postage included.
Last year my sister got married in August. Her H and her both got themselves NY Strip while the rest of us has broasted chicken. She then complained that her pepper steak was too peppery. She tried telling me it is common for the B&G to have different food than the other guests. She didn't believe me when I told her it was completely rude and guests make bad assumptions to that.
