I accepted a job offer at Geico almost a month ago with the start date being next week. Thought it was weird that the interviewer didn’t ask me if I had any questions, which I did. He didn’t give me a chance to even squeeze it in, but afterwards he offered me the job. I felt pretty off about the whole ordeal but I still accepted because I wanted out of retail. So i decided to accept the offer while I still looked around. I got an offer for a better job in a field I’ve been interested in for a while and background check has passed and all the paper work is done, so I start next week on the new job. Only dilemma I’m facing now is that I feel pretty bad about turning down the first offer, even though I know they’d fire me in a heartbeat. How do I politely decline and not feel bad afterwards? (I live in an at will state)
