Company offering a discount to sell items to clients

Q: I’m an architect. I design residential buildings for my clients and take design consultancy in return. Yesterday, a marketing team visited me. They were selling LED lights. A single light costs $10. They offered me a discount of 20% if I recommend the lights to my clients. They also said that if I sell the light at full price to my clients, they will transfer the remaining 20% discount into my account. If I give a 10% discount to my clients, they will transfer the remaining 10% into my account. Also, it is in my authority to give a full 20% discount to my client. Is this arrangement permissible?.

Handling wine in a supermarket

Q: I work in a supermarket where I have to handle alcohol products such as cases of wine, beer, etc. Sometimes, the products also break and leak onto our clothing. I have requested not to work in this area as I understand that handling and being involved in the transportation process of alcohol is forbidden according to the Hadith. The company requires some confirmation and clarification on this matter. I would be very grateful if you can clarify that this is haraam for a Muslim, as I need to prove to the company that I cannot work in such an area as a Muslim.
