There have been all sorts of nonsensical, arbitrary, and inconsistent practices across the the various H stores, that I gave up trying to figure out the specific "rules" many years ago, beyond the usual common sense approach to interacting with SAs. Hearing about these sorts of shenanigans is a total turn-off (and good protection for my bank account). I am lucky to not feel the need to buy anything from them at the moment or in the near future.
