From the early 1930s through the early 1960s, the chain served much of its food not in take-out containers but on inexpensive porcelain dishes with the "Krystal" moniker. The waiters and waitresses wore white uniforms, and food was offered through counter service. In the 1950s, Krystal opened its first drive-through window - which most locations maintain today. A 2013 study of seven fast food franchises found that service at Krystal drive-throughs was the slowest, with an average wait time of 218 seconds. It was, however, the most accurate in terms of fulfilling orders.
