Selling alcohol, tobacco, and other products that require identification. Well, because you get the morons who bring in their friends, and don't understand the law. Why don't people understand I have to ID everyone? Yes even your so called "non-drinking" buddies, and underage friends who forgot their wallet in the car. Has these people never have a retail job or figure out the reason why you were left in the car while your Mom or Dad bought the beer? It is also bad when the person doesn't have his/her ID. Listen, it isn't my job to prove that you are of legal age. It is your job to prove it to me. If you don't have your ID with you and you look under 40, get over it. It is your fault you didn't bring your ID with you, not mine. The shitstorm I have to deal with from people is unbelievable because they don't understand the law. Hell, next time you get denied the sale go scream it to our government it isn't my fault these laws exist. Sorry, I had to rant. Other then that I enjoy my job.
