Back when I was 18 or so I had my first office job. We punched a time clock. The time clock was located at the end of the warehouse far away from the office.
One of the warehouse guys lived near me and did not have a car. I picked him up every morning. As a courtesy, this guy would punch me in when he punched in. That way I didn't have to walk the warehouse and back, and could go right in and answer the already ringing phones.
This got both of us in trouble once when it was observed. The warehouse guy (who was a vital employee) pointed out that if he was there it was because I drove him, so I must be there too. I punched myself in thereafter until the day I walked in and didn't answer the phone and the owner noticed. It was soon deemed OK for the warehouse guy to punch me in.
Sometimes practical rules are impractical. It was this time especially. I was the guy doing the payroll every Thursday. No one ever checked my time card but me.l
