The chances are, you probably know your profession inside out. But after discovering this Reddit thread, where users were asked to reveal secrets only people in that line of work would know, we've realized there's a LOT we could be learning.
So scroll through this list of shocking revelations and life hacks, and learn a whole host of things you may or may not have wanted to know.1. Dentists: It's not always your best interests they have at heart.
"If it's a large cavity we will tell you that the tooth needs to be pulled instead of filling it because it doesn't cost us any materials to pull a tooth (except gauze and the anesthetic cartridges). I have worked in three dental health clinics and have seen this done too many times to count."2. Supermarket workers: Always take from the back.
"The oldest food is in the front. Get in the back of the shelf for the stuff that will last longer."
3. Hotel staff: Those beds aren't always QUITE as clean as we'd hope.
"The down blankets are not always washed, only the sheets and thin blankets. The top cover is only washed on occasion but not after every check out. I don't know if all hotels are like this, but the ones I worked at are." -Anonymous4. Baristas: Be nice or you won't get your caffeine fix.
"As a former barista, if you treated me or anyone on staff with a bad attitude, you most certainly were given decaf espresso. I did that for three years and nobody ever noticed/complained. DON'T MESS WITH PEOPLE WHO HANDLE YOUR FOOD."
"At Starbucks the only difference between a grande and a venti is that you get more milk. You pay extra for a little bit of milk. No extra coffee. Unless you're getting a flavored drink. Then you also get one more pump of flavoring. Really, though, it's not worth it for espresso drinks." -Anonymous6. Food product makers: It's all the same underneath the packaging
"Food products: one brand is the exact same as the other. [Real life] experience: "OK 'pause' the production line so I can change the packaging to 'Great Value.'"7. Visual effects artists: The television world is one great big filter.
"Everything you see on television is fake. Or at least enhanced."
