Pros
Flexible hours. Skills needed to learn are easy. Staff is nice and are open to any questions you may have. Most training is learned on the job.
Cons
If the store is busy, prepare to be worked to your limits. Generally, busy stores need the full scheduled staff, callouts mean disaster which leads to delays in production and the lines tend to get long which leads to rowdy customers. Pharmacists at some stores may not come to contain a situation which involves a violent customer - be prepared to handle such situations on your own. When you first start, they may make your stay at pick up(register) most of your shift and if you don't show motivation this may result in them forcing you to stay at pick up. This can result in not being proficient at other stations.
