The post discusses a study that explores the correlation between the proximity of kebab shops to train stations and the quality of the kebabs. Most comments critique the study's findings, pointing out the weak statistical significance of its results and sharing anecdotes about food quality in similar locations. There's a consensus that while the study might not have found a strong correlation statistically, anecdotal evidence suggests that food quality often declines closer to high-traffic transit points. This is attributed to the balance of high operational costs in premium locations against the sheer volume of service demanded. Interestingly, a few commenters note that this trend seems to be an exception in Japan, where food quality near transit hubs can still remain high.
