you'd think a combination of a degree in applied mathematics, a minor cataloging mentality and a major obsession with SONIC would give me a definitive answer to this question ... but, surprisingly (to me, only, perhaps), i only have guesses.
my experience has been that any given visit to a NV SONIC has something like a 40-60% chance of getting a survey receipt.
there are a number of things that might come into play here:
- the interest of the franchisee
- the area of the country the SONIC is in
- individual items that are ordered
- the financial success of any individual store within the chain
- health reports on any individual store
so your odds may vary widely. it wouldn't surprise me at all (in fact i'd go so far to say that i "expect") if your chances of getting a survey receipt in long island are different than OK city.
i tried calling the 800 number to see if i could glean more information before i wrote this post, but was put hold. this is precisely the kind of question that the customer service operators there will have no clue about ... mostly they regurgitate the stuff that's already online (and in some cases they even miss that). i'll call again at some freak hour (so i don't have to hold) and update this if i get more information ... but i'll tell you right now, the odds of that happening are MUCH lower than those of getting a survey receipt at SONIC.
