Has anyone worked as a security guard in a department store before? If so, is it a high stress job?

I decided to do security because working in a gatehouse affords me the time to study on the job, but that job has come to an end now, and all I'm seeing so far is retail security work, but IDK whether to apply because I just keep thinking about how stressful it would be to have to deal with shoplifters each day, and probably getting into a scuffle, or they pull out HIV syringes and threaten to stab you with it.

Do you experience things like this everyday in such a job?
