Wanting him out at first
Marianna was afraid that having any hobo in her cafe would scare off any potential paying customers, so she did not want them there. She then made an effort to re-enter Tom outside and back into the rain. She simply could not be handling this at this time. But then the homeless man showed up with a surprising proposal.
Helping out Marianna
He offered Marianna some assistance in the cafe in exchange for being allowed to stay until the rain stopped. He claimed to have had some prior experience working in restaurants and was open to trying anything.
