My daughter (then 15) had somewhat of a similar situation. She was working at  a shoe store and was told that because of her age she could not use the small stool to retrieve shoes from the storage room. She was let go because she couldn't use the step stool and it was heartbreaking to her as she took the job to buy Christmas presents. She did find other jobs and at one point had 3 jobs in the summer. Its seems to be rarer to find truly hard working youth that know it takes effort and dedication to reach their goals.
