During my tenure I frequently had ETLs come over with guests with instructions to fix them a free "whatever they wanted" because of a screw-up, a delay, cup got thrown away - whatever.
We also had TMs come over for free drinks from ETL/TLs because they got a red card, they stayed late to cover call-outs, they cleared the line, wore their name badge, did their zone, whatever.
But SBTMs could get green on Steritech/city health back-to-back, have green service scores, an outstanding visit from the DM & we got zilch.
