I ordered some beer off Drizly a several days ago. The liquor store is only about a half mile away, but still I tipped 10 bucks on the website. The guy comes to deliver the beer and with Drizly you have to scan your ID so I talked to him. I asked if he got the tip. He said no, the storeowner kept it. He showed me his app, and there was no tip listed. I re-checked my receipt, and sure enough, I had paid for a tip. I ordered again a few days later, this time from another store that was farther away. I tipped 5 bucks on the site and gave the driver 10 in cash when she showed up. Again, I asked if she had received the tip through the app. She didn't. She showed me her phone. This time it showed a tip, but she explained that the storeowner made her use the store's phone, and that he just paid her a flat cash rate for each delivery, regardless of how much the customers tipped. I got mad at the business owner and she begged me to please not leave a review because she didn't want to get in trouble for telling me that her tip was being stolen. The lesson here: tip with cash. Drizly seems especially prone to allowing storeowners to pocket the tips, and most drivers are working fully on a contract basis and have no way to push back against theft. If they complain, they are replaced immediately. And also consider leaving like a buck as a tip on the website and then asking the driver if they received it. That way you can see which places do or do not deserve your business.
