Hmm, this is a tough one. Michael's 15 years of experience as an Assistant Manager at Food Basics is impressive, but the specific job title and industry don't seem to have a direct correlation to a high-paying hourly rate. Considering his education in physics and the retail industry's average salary ranges, I'd estimate his hourly rate to be on the lower side, likely around $25 per hour, which is more in line with entry-level or part-time retail positions.
