Lying about employment dates on a resume?

I have worked in the food industry for about 3 years now but between moving houses and changing jobs I have worked at 6 different (mainly service industry) companies. Is it ok to just combine dates to condense my resume or will hiring managers find out? I was a server at most of these jobs so I wouldn’t be lying about any of the responsibilities.

example: I don’t think it is relevant that I worked at a large chain for 3 months so can I just say I got hired 3 months earlier at my current job that I’ve had for over a year?
