Yes, it's very likely that the restaurant staff will remember you if you're a regular customer, even if you're known for being notoriously cheap with leaving tips. Restaurant staff often have good memories and tend to notice frequent customers, especially if they have specific habits or behaviors that stand out.
However, it's essential to understand that being remembered may not always be a positive thing if you consistently leave small or no tips. Servers and other restaurant staff rely on tips as a significant part of their income, and being known as a consistently poor tipper may negatively affect their perception of you as a customer.
While the staff might remember you, it's always a good idea to be courteous and considerate during your visits. If you can't afford to tip generously, it's still polite to leave a reasonable tip that reflects the level of service you received. If you're a regular at a restaurant, building a positive relationship with the staff by being polite, respectful, and appreciative can go a long way in creating a pleasant dining experience for everyone involved.
