Don't be afraid to say yes, unless the job description requires years of experience, in which case you shouldn't have applied. Best to list jobs that sound harder than what you'd expect the grocery store's atmosphere, and ones that are relevant to the position your applying for. Pole dancing is a difficult task, but has little relevance to being a cashier. Now would be a good time to proactively mention any leadership positions you've held in the past that you didn't get paid for, like boy scouts or team captains, in case the interviewer doesn't ask later in the interview.
