So, what do you think is the biggest change(s) of how customers "buy" over the last few years (including COVID and pre-COVID) in terms of the traditional linear consumer model of Problem/Opportunity Recognition > Search > Evaluation of Alternatives > Buying Decision > Actual Purchase > Post Purchase Evaluation?

Has the Retail Market adjusted to this change? If so, why? If not, how can they?

Lastly, lots of articles in the WSJ and New York Times recently about how commercial real estate is tanking given everyone is Door Dashing/ordering from Amazon and office space prices is plummeting in Manhattan due to working from home (which was happening pre-COVID with telecommuting to some extent, but not ANYTHING like now obviously), so HOW should primarily brick-and-mortar retailers adjust going forward as far as financial investment in their physical stores? Should they keep building new locations? If so, when does it makes sense? If not, should it be in drive-through/pick up OR should it be almost all their budgets into ONLINE/delivery, etc.?
