I can guess the insinuation, but these norms were in place, culturally, across the spectrum. Sure, some castes (like Brahmins) have had stricter rules, while some had laxer ones (for Kshatriyas, Vysyas & Sudras) But I do know that eating out and eating only freshly cooked food was always the norm. Also, Dhabas and Street Vendors, are a relatively newer thing, starting up in about 1800's.
