>>33284668 (OP)>just to avoid sitting in a barber seatFor me it was a convenience thing and during and post covid it became a new habit to cut my own hair.
Note that buzzing off with a #3 guard will not look that good, but it won't look that bad and it will absolutely look better than waiting 8 months between cuts.
I don't have the patience or spare time to wait an hour for the walk in hair cut and I have a hard time with appointments justifying paying someone $50 to use a $25 hair trimmer the same way I would.
That said if OPs only problem is conversation, try to find a place that blasts music or sports on TV and nobody talks at those places.
