If albumin is detected in a urine sample collected at random, over 4 hours, or overnight, the test may be repeated and/or confirmed with urine that is collected over a 24-hour period (24-hour urine).
Say, for my $20 pedicure, I gave $3 tip to my foot scrubber and leg massager/toenail painter. The 2 ladies I went with gave nothing. It felt awkward, but my husband having worked in the restaurant and retail worlds, insists we tip due to personal experience. If your facial is $40, tip $6-$10. I average on an 18% scale, but 15-20% is perfectly acceptable and very generous. For mother's day, we give my mom a hot stone massage and a pedicure. We always send her with $25-$30 extra for tips.
My haircuts are about $12-13 and I always tip $2. I have no relationship and don't expect anything, I just think it's a profession that you tip. Like some other tips, I always give the tip to the hairdresser in cash rather than on my card, so they can decide how to chalk it up. I normally tip $1-2.
