Im not a taxi

My boyfriend and my sister’s boyfriend both went for an interview at chewy. I said I would take them IF THEY BOTH GOT THE JOB. My boyfriend ended up not getting it but my sister’s did. Now words are being put into my mouth saying that I offered to take JUST HIM. Now... this job is 45 minutes away. I’m expected to take him and pick him up Monday through Friday. He plans on giving me $10 a week for gas. HOW IS THAT GOING TO LAST ME ALL WEEK IF IM DRIVING 45 MINUTES ONE WAY. If I don’t take him, everyone’s gonna be pissed off at me. He got a check from his previous job on Friday that he has yet to go get. I’m sorry I just hate when words are put into my mouth.
