Assistant managers?

My son worked at Wendy’s in Lafayette, IN on Veteran’s Memorial Parkway during high school approximately 2017-2020.  I just recently found out WHILE he was in rehab for alcohol addiction that the assistant managers at the location he worked at had been buying him alcohol when he was underage.  I wish I would have known it at the time, but felt it was necessary to let you know because some of those assistant managers still work there.  They should not be working with high school kids if they are willing to do this for them.  It is illegal to alcohol for minors.
