No, two's the minimum for me. I always manage to find time for at least two.
2 passes minimum.
Life too short for abbreviated shaves. If I sleep late or am otherwise behind schedule, I'll make the shower mega quick, skip breakfast or wait til I get to work for that first cup of Joe. However difficult or harsh some of these sacrifices sound, I'll gladly make them in the interest of a proper shave. If I'm really pressed for time, I'll do a two pass shave but as a rule, 3 or 4 pass shaves are the norm.
Skipping a cup of Joe for a shave is true dedication. I take mine to the sink with me and toss in a couple of gulps when I don't have any lather around my mouth.
No, two would be the bare minimum.
However if I don't have time to complete my normal shave, I won't shave at all.
I can get away with 2 passes on my DE, but if I've left that little time I cant manage that much, I'd normally skip it all together. If I had to shave in a real pinch, I'd be pulling out my Sensor Excel.
