I have went to Sonic Drive in several nights in the last two weeks and I arrive about 9:45 PM I sat there until about 9:58 PM and a worker comes over the speaker and says their closed. I went 2 nights later about the same time sat there about 5 min they told me the shake machine was broken. I went last night got there at 9:48 they said the shake machine was being cleaned. This store closes at 10 PM from my past fast food management experience customers that arrive before closing time are to be served.
