All 3 in the bakery I worked at when I was in college. To summarise the stock, you could buy full cakes for £35, those same cakes cut into 12 and sold by the slice at £3.50, and mini cupcakes in all the flavours were introduced as a sort of generous sample size. I recall they were about a quid.

Man 1: orders one of the quid cakes on his lunch break. Came back after work to ask for a free full size slice of his choice because he’d taken a bite of his mini and didn’t like it. Was refused, these are 2 bite mini cupcakes to work out whether you like the flavour or not and you don’t, tough shit. He tried again the following day before work, pulling the same manky half eaten scrap of cake out and was refused again. Tried again on his lunch break, refused again. Took his final shot after work, and when refused he just chucked it at me. Grown adult in a formal suit working in central London, for context.

Man 2: comes in and asks for half a cake. Just take a whole cake and cut it in half but don’t make slices. I agreed and cut one in half in front of him, and let him know that there’s no “half cake” option so on the till it’ll be calculated as 6 slices (£3.50 x 6 = £21) and NOT as 50% of the full cake (£35/2=£17.50). He spent a good 5 minutes making himself red in the face screaming about “I don’t want slices. Why do you keep fucking talking to me about slices. How are you this stupid. Do you not speak English? It’s like talking to a monkey!” His requested “half cake” was sitting on the counter in its open box in full sight throughout all of this. He could see it hadn’t been cut into slices. Stormed out and didn’t buy it since “this thick fucking idiot is refusing to listen to simple instructions.” His partner/wife looked like she wanted to die. The vibe was like Ronnie Pickering and his wife just disassociating pretending she’s not there lmao.

Woman 1: the brand of the bakery was a sort of “friendly local” vibe so it was pretty normal to make drinks prior to payment. An American lady orders a hot chocolate, then saunters out the door to take a phone call. She gestures “no” and walks off down the road so her drink has to be thrown. It wasn’t powder hot chocolate, it was “real” homemade with chocolate, cream, milk, vanilla pods that didn’t generate much profit. She returns about 15 minutes later and now asks again for a hot chocolate, this time I request payment before starting. She goes MENTAL even coming behind the till to scream right in my face. Pretends to take a phone call and said “yaaaa call me back because I’m in the middle of something with a stuck up BITCH” followed by some incoherent racist babble. Switches to accusing me of being racist refusing to serve her because she’s Hispanic? At this point I asked her to leave, I had no authority to do that but yeah lol. She now insists she has diabetes, her blood sugar was low and therefore I HAVE to serve her or else she’ll report me to the “department of health.” Told her there’s a Pret down the road, get a snack from there and use their WiFi to do it.

Mental scenes.
