People who work in the service sector will have heard them before and most certainly won't think you are super funny.
For example, when an item at the cash register fails to scan, don't say "well. I guess it's free then". Literally everyone knows that joke. Here are some alternatives:
- *Covering your eyes* Maybe it can't do it with us looking.
- Can't blame the thing. I get shy as well when you point a laser at me.
- Maybe that one's to cool for a simple beep and is working on a symphony. Give it some time! I'm sure it'll be a masterpiece.
- At least we can be sure you're not a poacher, since you're quite bad at shooting zebras.
