Almost all the POS keys I got in the crap bag were DSA, many of them directly from the Ruby layout shown (fuel, view, ticket print, qty, cash total, etc).
There were a few DCS profile, almost all equivalent to top row Cherry profile, with four that were QWERTY row cherry profile. The Q row profile four are the yellow blank and answer, orange blank and ReCall. Only 4 vertical DCS keys, 2 squashed and the enter and rather nice cyan one shown here. Anything like that more what you were thinking of ergonomic? Other crap bags may have a wider DCS variety, or let me know if any here would help
