I get this one at least, without any problems, but only on a generic/habitual
reading.  For me there is a clear contrast between:

(1) At gas stations in the 1950s, a uniformed attendant checked the oil
and washed the windshield

(1') When I went to the gas station this morning, a uniformed attendant
checked my car's oil and washed the windshield

For me, (1) is OK if different people do the washing and checking,
while (1') isn't.  But I think I'd argue that the generic version isn't
really distributive.

(I'm using USian examples, because 1 is adapted from a novel I just
read, which unfortunately used a bare plural.)
