Looking up statistics, shrinkage rates at a grocery store are typically 2-3%. Theft appears to be about ⅓ of shrinkage (food spoilage is a bigger cause than shoplifting), so about 1% of revenue amounts to theft on average. The larger supermarkets seem to pull in on the order $100-150k/day in revenues, with the median half of that. So... yeah, the numbers don't add up. If it's $10k/day, even at an extremely large store, that's 6-7% theft rate. Given that grocers aren't high-margin, that's stark enough to wipe out any revenue. $1k/day theft rate is a more reasonable estimation.
