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.
If you get a good pedicure with a really awesome nail technician, you should tip them at least $3 or 20% of the total cost of the pedicure. But you can always tip as much as you want. Seeing someone brighten up because you have tipped them more than they had expected is a wonderful feeling.
