I checked in at normal desk, with a check in agent.
My name started with the same letter as the other pax, but is shorter and Anglo Saxon, however as someone with some pyschology education, I can understand how the brain could "see" the two names as being the same, fro emaxple yuo cna reda thsi, becuase the brain interprets general patterns, not exact words.
However, I suspect this was not the reason, I suspect that she issued a duplicate boarding pass for the pax who checked in immediately before me. In other words a typical human error.

Funny you should mention that, one of the highly trained BAA personnel working in the landside area did make a joke about whether I was carrying foundation, lipstick etc, but I don't criticise him because (a) he displayed a sense of humour (rare) and (b) he did not handle the pass
