I think it mostly depends on what it is and how it is packaged. I do pay attention to exp dates, when shopping, I'll reach to the back to get the "freshest"! Most things, if in doubt, I'll smell, but usually chunk if in doubt. Really picky about sandwich meat, even before checking date, I smell and feel, if it don't smell right or it's slimy, it is definitely chunked. I hate wasting also, but I'd rather go hungry than to get sick on bad food. JMHO
