It rained all day today .. I worked from 8am/ to 3pm today ..

During my shift an elderly homeless man who couldn’t even hold a sentence together asked for some coffee ..of course!! I even bought him some cookies for the road .. later in the day my 2nd shift arrives and this dude comes back for more coffee.. I’m a little hesitant because now I have eyes one me .. but I tell him “go head” and my co-worker was like “he’s not even allowed in here” .. I told her he just wants coffee and I’ll pay if he steals something ..i clock out at 3 and around 4 my boss calls me and tells me my co workers keys are missing ., and if I let anyone in the store that shouldn’t be in there .. somehow in my head I know this isn’t about missing keys..
