Evening and part-time openings around Atlanta - any advice?

I am looking for part-time work that fits around school hours and found a few evening shifts near Atlanta. Shifts are four to six hours and the pay is weekly. How many hours do they guarantee?

I got the job by going in around mid-morning and asking for the manager. Worth a try.

I worked evenings at a hotel. The hours were steady and the team was friendly, but weekends were busy.
