As others have stated, that might be middle of the night for some. For Brad, it sounded like a stop off on the way home after working and then going to the gym. How many purchases do you think they will find between 6 a.m. and 7 a.m. on any given Saturday?
Evidently they must have found some - otherwise this would have been pointed out and emphasize by the pros, Cummings: "BC never went to the grocery store between 6 and 7, first time it happened".
Heck, even if they had said "first time in months".
No mention...so not an issue.
