@lnxw37a2 The assistance aspect didn't seem to slow down the overall experience for me, but yeah, the 1 or 2 employees always seemed to be helping people, so if you happened to need help yourself, it was often a small wait.
This may be lessened here in California because CA does not allow for alcohol purchases in self-checkout (which is moderately stupid), so the employees aren't doing ID check lockout overrides for people buying beer.
