Struggling so much working at my grocery store

Struggling so much working at my grocery store I am a bagger for a grocery store and if a customer has milk with them I have to ask "Would you like a bag with your milk?". This sentence is so hard to say for me. It always comes out terrible. To add on to that I have to wear a face mask so it makes it muffled. It takes 3 tries sometimes to get the customer to understand what I'm saying. Thanks for reading I'm just venting.
