should I be concerned ??

So my boyfriends mom works at a bar and had to work yesterday on mothers day . So me and my boyfriend made her some chocolate covered strawberries and bought her some flowers to take her . So when we get there this waitress that's always there and knows who we are looks at him and goes "are those for me !?! " and she gets super happy and I say NO! And he does also so sh goes "oh? Are they for your mom then?" Like she really thought they were for her . Also after that she started talking to her friend (another waitress) and they kept looking at me and laughing and than her friend goes to his mom asking "did TYLER or NICOLE make these ?" And than she walks away laughing! And they just kept walking in front of us laughing and talking with him and his mom . She's never even talked to us before or anything so I feel so weird about the whole thing ! Also , keep in mine the waitressing side is on the other end of the building with a whole wall in between so I don't understand why she had to keep coming and hanging out over there. Should I feel like something fishy is going on ?
