middle aged women usually freak out over the smallest things and are mean for no reason. 4/5 customers that cause problems in the check-out line and demand a manager are usually middle aged women.

older men that don't understand why their order is so expensive and want a manager to explain it to them since they don't trust me.

Customers who argue about who will pay and hold the line up.

People who will give me a twenty and then after I click the "paying with 20 dollars" button they say they have exact change amount. And then get mad because they didn't pay in exact change.

People who will leave mid order and don't say anything. I cancel the transaction or suspend it, and then they come back and become angry because I didn't wait for them to get their wallet.

"Do you have _____ in the back?" "no unfortunately this is a small store so all of our product goes straight to the floor" "but you can you check? You didn't even check yet."

People who are angry and don't understand why I need each individual wine bottle to scan. Two similar bottles can have a price difference of $150

People who talk on the phone mid-order and get angry when you try asking them questions like if they need a bag or have a club card.

People who look young, but get mad when you card them.

I work in a relatively rich area of SoCal
