"Build that wall Trump daddy." That note, left on a receipt at an IHOP in Virginia, was reportedly written by a group of teenagers after they finished their meal on Saturday.

The waitress, Rachel Mau, told WFMY News that she'd never had that kind of an experience in her nearly five years working at the restaurant.

It wasn't the service, she insisted. She had served the group the prior day as well without incident.

"I felt like they were assuming I was Mexican," Mau told the local CBS affiliate on Monday.

She said the note "really hurt my feelings, and I was very upset at first." 

Trump campaigned on a platform that was harsh toward immigrants and tough on immigration.  

A Pew Research Center poll from November found that "59 percent of people who said they strongly support Trump thought undocumented immigrants were more likely to commit serious crimes" and "41 percent of people who strongly support Trump thought undocumented immigrants were taking jobs Americans want," Time reported. 

Since the election, the SPLC has been keeping track of hate-related incidents deemed the "Trump effect." In a survey of 10,000 K-12 teachers and school administrations released in November, the SPLC found that 80 percent of survey respondents "report heightened anxiety on the part of marginalized students" and 40 percent "have heard derogatory language directed at students of color."

Beyond the offensive message left on the receipt, the lack of a tip exposes another issue: tips are meant to subsidize the minimum wage for employees who receive part of their compensation in tips. The federal minimum "tipped wage" is $2.13 — as is Virginia's, according to the U.S. Department of Labor — and those employees rely on tips to make a living wage.
