With or without a mop when shopping

As a mother of 7 kids there are always mishaps .....as my kids want something to eat or something to drink when going to the mall.....unfortunately the staff that is employed at these companies are not taught etiquette at all.....my youngest son had a mishap with his juice as i was leaving the store ......i do not walk around with a mop in my pocket!!!! I did not notice the mishap as i was looking at an item while leaving .....the lady who sanitizes when entering the store walks up to me and demanded in my face what happened on the floor ,as taking notice i see my baby had spilled his juice .....so i apologise and say to her ,i think my son dropped his juice .....she stood looking at me as if to say what are you going to do about it.....then she walks to the security guard and complains in her language ,pointing at us.....feeling very uncomfortable i decide to leave the store as i leave she starts pointing at the mess saying who is going to clean it up .....pointing at me ....pointing at the mess....unfortuanately mishaps happen....it is not on purpose at all .....but is this the way staff treats customers ....where is management at that time.....
