Note the knobbys on that cruiser. It is not exactly a race and taking time for a tire change seems to be a pretty good idea.
And then there is that famous school of thought who's primary directive is, "A clean bike is the sign of a rider doing it wrong."
Variations on theme:
If you have time to clean your bike, you are doing it wrong.
If you don't have to clean the part of your bike to work on that part, you are doing it wrong.
If other riders do not tease you for having a dirty bike, you are doing it wrong.
If you park in a lot and other bikes will park near your filthy bike, your bike is not nearly filthy enough.
If you have to take your bike to a shop for service and they don't tell you that they won't touch it until they or somebody cleans it, you are doing it wrong.
If you invite a hot babe or other SO to sit on your bike for selfies and the filth does not make them decline, your are doing it wrong.
If you invite little kids to sit on your bike so that parents can take pics and the parents do not scream at the kids "don't touch that filthy thing". you are doing wrong.
A lot of the above transfers to riding gear:
If your riding budds ask if you washed your riding gear and your answer is not, "No, I got caught in a 4hr frog-strangler", you are doing it wrong.
If you get caught in a frog-strangler and you do not whip out your Dawn Dish Spray and take advantage of the moment to spritz your gear and your bike midst transit, you are doing it wrong.
and so forth,
