Considering the situation described above, the impact a 15 minutes lateness would cause those I work with and the spa's clients are "<u>negative</u>."
<h3>Who is a cosmetologist?</h3>
A cosmetologist is a professional or permitted to deliver cosmetic treatments to the hair, skin, and nails.
Should a cosmetologist be late on his first appointment, such a person would delay the work of others he works with and delay the clients to get their work done on time.
Also, such lateness might change the mind of clients and those he works with towards him as unprofessional.
Hence, in this case, it is concluded that the impact would be <u>negative</u>.
