To pick up some food items that I wasn't able to purchase at Clifton Morrison's, I took a long walk and then rode a bus to Gamston Morrison's, as that store is larger and contains a greater selection. I spent fifteen or so minutes in the store and then returned to the bus stop; however, the next bus was in 25 minutes and I had no desire to wait.
As such, I walked to West Bridgford from Gamston Morrison's; at a point during this walk, I saw, going in the direction of Gamston, the bus that that I would have taken had I waited. Some twenty or so minutes later, once I had nearly reached the stops bound for Clifton, that bus appeared again. I beat it by a minute.
While I only saved myself a minute of time, which was negated anyway by my having to wait for the Clifton-bound buses, walking from Gamston to West Bridgford was still beneficial, in my view, because the exercise performed while doing so was preferable and better for me than waiting around for nearly half an hour.
