At least here in the U.S., gina , that may or may not be true in that while the Federal Minimum Wage is mandated, that is only somewhere around $8.00 per hour. Our friends at Wikipedia explain "...Some types of labor are also exempt: employers may pay tipped labor a minimum of $2.13 per hour, as long as the hour wage plus tip income equals at least the minimum wage. Persons under the age of 20 may be paid $4.25 an hour for the first 90 calendar days of employment (sometimes known as a youth, teen, or training wage) unless a higher state minimum exists..."
Hence, some modes of employment (waitering as example) can be paid hourly significantly less as long as that plus tips equals the minimum, but most people that are waiters or waitresses choose to work at places known for producing high tips consistently.
I've friends that make as much as $50 hourly when considering the tips they average, so, obvioulsy, they are not too conderend about the required hourly minimum.
It should be noted that while there is the Federally mandated minimum, several individual States have minimums quite a bit higher... maybe $10 to $15 hourly.
Ironically, this higher minimum wage has reduced employmnet percentages since the minimum has priced the typical 'hamburger flipper' out of the market because the McD's, etc., can't charge enough for their product to cover the significant additional wages...
