Ajay Brewer was far away from his coffee shop, Brewer's Cafe, upon receiving his wife's call about a particular customer: America's First Lady.

Jill Biden, entourage and secret agents to buy coffee at the shop in Richmond, Virginia on 24/2 without notice.

That day, the First Lady of America went to Richmond to visit the Massey Cancer Center at the Commonwealth of Virginia.

Brewer's Cafe is a family of color shops located on a small street in the Southside neighborhood in Richmond, where people of color predominate.

Before that, she bought cakes to celebrate Valentine's Day at Sweet Lobby, a famous bakery in the Washington capital of Winnette McIntosh Ambrose, immigrant from Trinidad.

These moves may be intended to represent the First Lady wanting to cheer for small businesses.

But Jill Biden clearly understood the power of appearances like this, like the one when she unexpectedly visited the National Guardians outside the Capitol and gave them cookies.

A person familiar with the first lady's schedule said stops like Richmond were selected a few hours or maybe a day before her arrival.

Unlike pre-announced visits that cater to the First Lady's agenda for education assistance, cancer research or the family of the military, no newsgroups followed Jill Biden when she arrived.

Gestures like Jill Biden's visits "can be both genuine and political," said Katherine Jellison, a history professor at Ohio University who studied the first ladies.

It may be true that Jill Biden wanted to show support for black shops.

Black female voters were the group that gave Biden a fervent support in the election.

Brewer was born and raised in Southside.

Like so many other small business owners, Brewer was in trouble.

When Jill arrived at around 4:00 on February 24, Brewer was 30 kilometers away helping a friend who had just opened the boutique.

Fortunately, Brewer's mother, Pamela, 58, is in the bar.

Jill bought two cups of coffee, a Poor Georgie oat cream cake and a Mr. lemon blueberry cake.

The visit was very short but had a big impact.

The owner of the Sweet Lobby bakery near Capitol Hill still feels elated two weeks after Jill Biden's visit.

That evening, Biden posted a photo of her shopping for cakes on Instagram, Twitter and Facebook.

Ambrose didn't know why Mrs. Jill got to know her shop.

Ana Maria and Stephen Bota pressed the photo they took with the first lady and placed it on a shelf behind the checkout counter at the Newsroom in Dupont Circle, for everyone to see.

The First Lady bought Time magazine with her husband's picture on the cover, Vogue magazine featuring Vice President Harris, Washington Post issues of the inauguration, and several women's magazines.

Maria and Bota have opened their own stores in various locations since 2004 and are now one of the few remaining newsstands in Washington, DC.

Stephen told Mrs. Jill that his store was open 7 days a week, 365 days a year, the only time he closed it was to bring the whole family to Delaware for the funeral of Beau Biden, the President's eldest son,

He said that Jill Biden's aides did a lot of research when choosing locations.
