Locally, before portables, this city had call boxes downtown. Walking beat officers had to check in every 20 minutes. One officer (who retired as major) had his own chair in one of the alleys downtown. He didn't smoke but he bought Pall Mall cigarettes. He would light one, put it between his fingers, tie the fingers together with a rubber band and go to sleep. The cigarette would burn down to his fingers and wake him up in time to go to the call box to check in.
