I did this for 2 months. I peed on the stick, popped the stick back in its packet, walked back to my office, took it out of its packet then laid it flat on my desk behind by PC.

Another option is to pee in a container (urine containers are great) then take it home and check later that night. I've heard that urine stays "fresh" for 12 hours so testing your 2pm urine at night should work.
