Because you still need to wait for the attendant to come. But you have no chance of scanning other items in parallel. (Assuming you don't know if this store will block scanning)
It is always optimal to scan these first. You have two cases:
Blocking: scan 1 + wait for attendant + scan rest
Non-blocking: scan 1 + max(
wait for attendant, scan rest)
The first case is never shorter than the second case.
