Working in retail is quite stressful no matter what your role is.
And when it's during busier periods such as New Year, Christmas, Easter and Halloween - just to name a few - it can be even more stressful.
Christmas is now upon us with people up and down the UK shopping for last minute gifts as well as getting everything together for their festive feast.

But despite it being a stressful time for us all, it can make all the difference when people are understanding towards the staff. And no, it's not their fault is they don't have what you need in stock.
Whilst it may seem obvious to be kind to retail regardless of the time of year, some people aren't and it can make the job all the more difficult. To quote Harry Styles, Treat People With Kindness.
And according to one former Tesco employee, people can be downright rude. Having spent many years working in their local store, the member of staff has lifted the lid on the things they would love to say to shoppers - but they're not allowed.
Some are funny and interesting, but others are really eye-opening. Here's what they want you to know...
1. I know it's three minutes until we open, but I can't unlock the doors just because you're standing there
Telling the Mirror they said that it's great that people are up and about early...but unfortunately when we open at 7am, that means 7am.
I'm sorry if it's raining, or you're cold. But looking at me with a face like thunder isn't going to speed this process up.
2. Huffing and puffing in the queue won't make me go any quicker on the checkouts
I'm not deliberately going slow - it's just busy in here.
3. We dread asking for someone's ID - and then finding out they're 30 anyway
Feel flattered I'm asking you to prove you're old enough to buy that bottle of vodka, because I'm not doing it for fun.
4. The Tesco fleeces are so incredibly comfortable
They aren't the most flattering items of clothing to wear, but they are amazingly warm in those chilly winter months.
5. The frustration of people gathering around you as you knock 30p off a pack of mince
Those yellow stickers are coming out, and its like shoppers can smell them a mile off.
6. The mindless game you play trying to squeeze another box of dolly mix on the shelf so you can finally get it out of the cage
We all know those huge cages can get in the way, but getting the products off them is the real task.
7. My lunch isn't a free Tesco meal deal, let me assure you
Going on lunch and finding yourself short of a few quid so you opt for that Tesco Everyday Value thick sliced bread that your managers generously left in the staff room.
8. That sigh you give when a customer pleads with you to knock some pennies off
The last box of 10 pack fish fingers has been opened - it's probably just a damaged box but hey, I'll knock 10 per cent off to avoid the drama.
9. The carrier bag charge is definitely not my fault
Rolling your eyes when a customer blames Tesco for the 5p plastic bag charge - I'm all for saving the planet, but don't take it out on the messenger.
10. Clocking onto loyal customers' routines
That's right, Barbara. I see you doing the weekly shop at 7pm every Wednesday.
I saw you last week, and the week before that, and the week before that...
11. I hate the self service tills more than you
And impatiently waving your product in front of the scanner isn't going to make my life any easier.
I hold the power to unlock these bad boys, and the red light flashing above you has already told me you need my help.
