Some people in the intertubes are upset about what they perceive as underhanded campaign tactics by the Clinton campaign here in the urban hellhole. It's standard practice for endorsing organizations, including the city party, to hand out filled in paper sample ballots (we have ancient machines for the actual voting), with the endorsed candidates listed, to people as they head into the polling places to vote. So, yes, the sample ballot I received helpfully told me to vote for Hillary Clinton.
As long as it's 10 feet from the polling place - a trivial distance - all of this is legal and completely standard in Philly elections. I'm not such a huge fan of the practice, but it isn't specific to the Clinton campaign or this election.
