When I was in Manila a few years ago, i ventured into a salon for a haircut and shave. As i was seated in the big chair waiting, a girl asked if i wanted my nails done - fingers & toes. I said, why not? go for it and it was fantasticly relaxing and enjoyable. A pedicure is of more worth to me, hard skin etc, as a manicure is wasted after 1 day back at work up to my elbows in ink and oil.
If you get the chance, try it. Its not the most essential thing to do but it is nice.
