Worried about work

I just found out that I will be going back to work on Monday and I'm honestly very nervous about it. I know the company will be providing me with masks and hand sanitizer, but I'm afraid that's not enough since I work in retail where I will be directly interacting with customers.

I'm just worried because my grandfather lives with me part time and he is at greater risk of being sick. And while he isn't going out, I can still bring something home with me from work. I'm also worried because I feel certain that we will have another wave later. I'm not going to quit my job because I need the money, but idk. I'm just worried
