Yes, many of the salad bars in the 70s and 80s didnt even have sneeze guards. Not that they do much, it all depends on the height of the customers. lol Hubby and I often did a Sunday brunch down at a 'posh' hotel in TO for birthdays/anniversaries/any old occasion and it was not like being with a cast of thousands. For many of the foods, you had a server ie at the hot food section. We even had our wedding dinner at a famous TO buffet, so that people could have exactly what they wanted. No rubber chicken meal on that day!
