Canadian Tire review: Disappointed with customers service and treatment

This happened in Canadian Tire Humboldt Sk
This was the situation I left in their website review.
-Disappointed, while I was at the store buying water, the tall bald guy who works in parts and service . Was ranting and being rude about their shopping carts getting broken that's why they increase the price of the water and etc...
First of all:
-Did they even ask or informed me about not putting 4 jugs in the cart.
-they never informed me that the cart shouldn't be used for 4 jugs of water.
-they never informed me that the cart has weight limit.
-And if there is how would I know ? ( I was never told about it).
-nobody informed me about it or even no one talked to me about it.
-I've been buying water from them since 2023
-Same scenario 4 water jugs in a cart.
The things is you don't have to be an "AH" about it, you could have just informed or ask me politely and kindly. Not ranting and being rude about it with the other lady customer in front of me.
There's a big difference between informing, letting know a customer kindly and politely. Than being an "AH" ranting and being rude about stuff that the customer was not even aware of for 2 years.
You're in a customer service industry, if you don't want to ask politely or kindly. You can always ask in a right manner of way with respect. I might be in a minority group but I do treat everyone with respect ,i encounter everyday.
Always remember this things;
-does the customer know
-do they know the situation
-are they aware of what's happening
If not ;
-how do i inform them properly and in a right manner of way.
-how to do it better and best way I can without disrespecting or being rude to others.
What ever's happening in your day today don't blame it unto others. Everything's gonna be ok if you're having a BAD DAY. But please do respect others. I don't know if you're the owner or what , but you don't get to disrespect or treat others like that especially you're in the customer service industry.-
This is what happened today. I've never experienced this from my 1st day not until today, here in Canada , I don't know if his just having a bad day or just because I'm from a minority group. I don't know if his just an employee or an owner. I do follow rules and regulations as long as I know and I'm properly informed. But what can I do if I don't know and they didn't even informed me. How would I know. Even if his just an employee or an owner that doesn't give him the right to disrespect, be rude or be a racist to customers like me.
